I'm guessing Brazil will be included in the expansion, for a couple reasons. It's a growth market, so it makes sense from a marketing standpoint and it has a rich precolonial history, with Tupi, Chachapoya, and other indigenous groups.
In terms of growth markets, Indonesia would be logical, so I'm guessing Majapahit too.
Since there isn't much in terms of Eastern Europe, I could see Poland-Lithuania being included.
I'd like to see the Pueblo included, since the western US is largely neglected, and a couple more American Indian civs would be nice, but with Brazil being likely, Kongo is a more reasonable contender, as Angola was also a Portuguese colony, and sub-Saharan Africa is completely unrepresented.
