Where are railways unlocked??
That´s a very good question.
Also I miss a Breech-loading rifle in the industrial era without the need of nitre. Otherwise a lot of Armies could have planes, artillery ans swordmen

That´s a big lack!
How does Jet-Bomber fits to the tech stealth?
I miss the cruise missile a lot.
I also wish there will be some Special forces like Paratroops, Marines, ore some fictionally unit.
Unfortunately there are a lot of other lacks in the Techtree jet for example its possible to get printing without writing. Well what will this Civ print is my question? ...and a lot of other.
I can´t say if I like the separation of the Techtree into two the tech tree and the Civic tree at the moment. As I see in the Civic tree video there are a lot of Social developments represented who have a massive impact to the tech invention. Most tech inventions are the consequence of Social changes and needs.
I am very hopeful the shown tech tree is not the final version!
Furthermore I like some aspects of the tech tree, so I like the balloon unit even if it will enormously strengthen distance units- maybe too much but good idea.
Thanks Marbozir for posting the videos
