Looking at this thread makes me think the rest of the civs are going to be a bummer. Zulu and Portugal are the only 2 civs left I'd care about, and it looks like Portugal is out. Do you think they're planning to release more DLC civs? Because at this point Portugal and Sumeria would be the only ones I can see selling well if they include the Zulu civ now. I know some people on the board want Poland, but do you see that selling well enough to bother making?
Point is-- either they're saving Portugal/Zulu/Sumeria for future DLC and will be giving us bummer civs like HRE, Hungary, and Poland now, or they're giving us Sumeria/Zulu now, and aside from Portugal this is pretty much going to be it for civs that a broad audience will actually care about.
Another thought-- while they're obviously not rolling all the DLC in, it is possible that maybe they'll just throw Babylon into it. It's the only DLC civ without a scenario and it started as a pre-order bonus, so that could possibly end up taking up a slot.
