I personally don't think an Italian Civ is in the cards at all, and I do think that Africa will get a representative of one kind or another.
Although it's not 100% yet, the leak of the Cree and Not-Gandhi goes to show that the trailer doesn't indicate every Civ that will be in R&F. Unless I am missing some clue, neither of them are referenced in the trailer.
Yeah, we've reached the point where it's no use examining the trailer for clues for upcoming Civs.
