At first this was going to be simple comment for 'BE Factions' thread but... I suddenly realised I have written too much 
This is IMHO complete vision of BE space sponsors/civilizations, each with other gameplay focus, philosophy, and they all represent all major world cultures and civilizations.
I am interested how much they will fit what we will see in game
First of them are basically already revealed by Firaxis
1) Panasian Cooperative - Production, Supremacy
International Corporation remaining as the greatest manufacturing superpower of Earth during the action of BE, thus having powerful production. Its preferred Ideology is Supremacy as Panasian Cooperative remains the second greatest scientific power after American Reclamation Corporation.
Chinese communist regime has finally fallen in 21st century, but China didn't transform into classical Western democracies, seeing them struggling with challenges of the new era, nor did it return to backward imperial state. Instead China chose its own way of corpocratic federation, remaining the greatest industrial superpower of all mankind, along with other members of newly founded Cooperative: United Korea, Japan, Taiwan, Vietnam, Tibet, Great Mongolia.
Panasian Cooperative is based on thousand years of East Asian technological ingenuity, dilligence and discipline. Still, it has many huge problems, from overpopulation towards global warming and sea levels arising, thus greatly endangering Vietnamese and Chinese lowlands. Panasian Cooperative is pioneer of space mining and colonization.
2) American Reclamation Corporation - Technology, Supremacy
Following the great economic Collapse of 21st century, not only China but also American united state has fallen. After decades of internal ideological conflicts the Second Civil War devastated the country... But also created the base for its rebirth. America refused to return to the old ways, instead becoming technocracy of American Reclamation Corporation and again emerging as great power.
America has lost much, but didn't lost its soul and intellect - with great technological legacy and still remaining domination on the fields of soft power, Internet and space technology, American Reclamation Corporation in the game remains as scientific superpower. Suggested Ideology: Supremacy.
Without as huge population and environmental problems as Panasian Cooperative, connecting Atlantic and Pacific, different America is again one of the world main powers. But now it has powerful opponents... Space Race is a chance for America to rise again. The leader is the Great Manager of Corporation.
3) Brazil Republic - Military, Purity
Brazil was world agricultural and cultural power for a long time but it didn't have the will to become true world empire... Until it has finally grown to maturity. The great turmoil of 21st century changed Latin America and its greatest country. Brazil didn't become any kind of ridiculous international corporation, nor did it remain as backward national state - Brazil connects worlds, nations and cultures...
Militarized Brazil doesn't care about religion, philosophy, nationality nor money of its citizens - it cares about their souls and their will to reshape the world! Brazil Republic, supported by millions of people from forgotten Third World countries, doesn't believe in passive resistance! Weak have to become strong in order to participate in the Great Game of History.
Brazil Republic believes in power of state and human being; only strenght managed to take Brazil into stars and only power of will will manage to support this dream. It relies on military power - suggested Ideology is Purity. The leader is the President of State.
4) Franco - Iberia - Culture, Purity
Western Europe was seeking for its identity... And managed to find it. Franco - Iberia refuses to join European corporations and remains the citadel of patriotism and great tradition which made Europe the greatest continent in the past. The union of Belgium, France, Portugal, reunited Spain and Italy is ready to defend past and shape better future.
Franco - Iberia isn't maybe as militarized or industrialized as former superpowers but it remains the greatest world cultural powerhouse. In the beginning of 21st century, 200 000 000 people were visiting these countries each year, and it was just the beginning of the European Soft Power. Franco - Iberia knows the humanity doesn't lie in purely materialistic things and its spiritual influence shapes the entire world.
Franco - Iberia in game remains cultural power. Suggested Ideology - Purity. The leader is the Prime Minister of Franco - Iberia.
5) The Crescent Company - Trade, Purity
One thousand years ago, the Golden Age of Islam has finished... And since then, Islam was no longer the center of world economy, culture, science and technology. The backward tendencies created very deep crisis for the entire Muslim world in 20th and 21st century, which resulted in the Dark Ages. Finally, after tears and blood spilled, the brightest people of this civilization created the Crescent Company - they understood that new times require new solutions, and where the political power has failed, the economy can win.
The Crescent Company, based on Muslim ethos and centuries of great merchant tradition, currently remains the greatest global financial and economical power. Its influence stretches from Mali and Morocco through Middle East to Pakistan. All international trade routes begin and end under the protection of the Crescent Company. United both by seeking money and great moral values, people of this massive corporation are inclined to begin the Second Golden Age of Islam - and they are ready to go into stars in order to achieve this goal.
The Crescent Company in game is all about financial power, banks, trade routes, economy and investitions. In space it seeks money, but in the money it seeks the blessings of God. Suggested Ideology - Purity. The leader is current Caliph from Nigeria, Olanyje Wataba Osuntoki. Main languages: Arabian, Persian, Swahilli.
6) New Russian Empire - Agriculture, Harmony
The Russian imperial power has fallen once and forever. However, along with it, the tragedies of Russian nation, persecuted by centuries of poverty and tyranny, also has disappeared. The entire Orthodox civilization has been terrified by the challenges of the new century, until the Great Patriarch Commennos invented the new way for Eastern Nations.
Third Roman Empire unites all Orthodox countries in the world, from Balkans to Russia, from Kazakhstan and Armenia to Ethiopia, but no longer remains terror of the world. Remembering the results of infinite autocratic power, the Orthodox Civilization returned to its true core - the brave pioneers and their families, and their symbiosis with great areas of East. Global Warming made cultivation of fertile soils on North even more lucrative, and along with an ethos of work and spirit, Third Roman Empire remains as the greatest agricultural superpower, feeding the world. The ruler of Third Rome is called Emperor, but it is Emperor of souls - the people of Third Rome are probably the closest to true democracy in the entire world.
Strong and brave people of the north are one of the first to colonize new worlds, understand them and live in a symbiosis with them. Third Roman Empire excels at improving terrain and its suggested Ideology is Harmony.
7) Greater India - Religion and Spirituality, Harmony
Only Greater India understands what makes a human being. Not hollow economy, not hollow 'culture' of Western Europe - the human being is trying to understand the world and seek peace in its heart. Evil in the world is caused by fear, and Greater India, including the entire Hinduist and Buddhist Civilization, based on the tradition of 'Hindutva', is the world center of religion, spirituality, philosophy and psychology.
People of Greater India live in the harmony with nature and the entire universe, more caring about cultivation than about money. The society of Greater India, enchanced by the social engineering of 21st century, is probably the most peaceful of all new civilizations. The goal of the Association is not Gross Domestic Product but Gross Domestic Happiness.
Greater India goes to stars to seek true Enlightenment and new values. In game it remains the religious and social superpower, perfect for finding Harmony with nature and building internal Utopia. Suggested Ideology - Harmony.
8) World Freedom Organisation - Colonization and Infrastructure, Supremacy
World Freedom Organisation doesn't believe in strict values of other superpowers, in ruthless economical domination, in weird cults of Greater India or New Russian Empire. The main value is human freedom and people of WFO are going to fight for it forever, even if they have to go to stars to get it!
WFO includes Great Britain, Germany, Poland, Scandinavia, Canada, Australia, democracies of Latin America, Africa, and everyone who seeks for liberty. It is the great sponsor of space colonization and it has millions of brave people willing to conquer new worlds for the case of freedom - the most important value of humanity and the best recipe for future.
In game WFO is the best at colonization of new areas, building advanced infrastructure and quick expansion... And defense of it. Suggested Ideology is Supremacy - the technology gave humanity an ability to remain free from terror of biological extinction, so WFO believes here lies true liberty of human mind, where biological body disappears...

This is IMHO complete vision of BE space sponsors/civilizations, each with other gameplay focus, philosophy, and they all represent all major world cultures and civilizations.
