I can see most of these. They would likely go with just a "Korean" culture for this era though. Vietnam, Ethiopia, and Japan are all good bets. I pause on Brazil simply because they would be the only South American faction after they decided on cutting Incas for release and i think it could be released as part of a DLC pack down the line (probably a relatively high priority pack though). I can see them going either way, in or out. I'm excited to see and just want more info already dangit!
