I do think Vietnam's chances are higher than I initially expected, if the Sofia CS theory is anything to go by - given that Belgrade is still in, the only other plausible CS --> civilizations would be Budapest/Hungary and Hanoi/Vietnam. I think Hungary would be a great addition, but given its somewhat overlap with Austria and Poland, I'm not sure whether it'd be in. Vietnam, though, would work well with BNW's new themes, it has a relatively easy choice for a female leader (for those who have some knowledge of Vietnamese history), and is relatively unique in Southeast Asia for being the only Chinese-influenced civ there (so it'd contrast with the already-in Siam and the other possible SE Asian civs)
Actually Hungary and Austria don't overlap that much
They only have to move the Hussar UU to Hungary (to it's proper place) and give a new UU to Austria
Hussars look strange with Austria anyway, they were never really a horse civ
Also, as it was brought up, Phoenicia also has a chance based on the military city state theory
Actually, I would love to see all 3 of them in Civ V, but there is no real chance for more then one in BNW
I can't really tell which one of these 3 civs have more chance, even if Vietnam leads it's not by much
