That's the main reason I think TES 6 is going to take place in a human province: Bethesda won't want to alienate new players by having the game set in a province full of, say, cat-people (in Elsweyr's case). Valenwood might be possible, since elves are much more common in fantasy worlds.

But I'm fairly certain it'll be High Rock or Hammerfell, with Hammerfell being the more likely of the two since it's much closer to the Aldmeri Dominion.
