Breakfast Topic: Where to next?

Okay, now that we know that Blizzard is already designing zones for the next expansion, my question becomes this - where is it set? Where are we going? Back to some lost continent on Azeroth? The Emerald Dream? The Dark Below? (I never get tired of that one.) Argus or Xoroth or some other world entirely? The Azeroth that would result if the Horde didn't invade it thirty-five years ago, so we can see all those cool Alliance heroes like Lothar and Turalyon and Alleria? Sanctuary? (Seriously when is the Warcraft/Diablo crossover going to happen already?) Are we going to actually go to Nexus, the setting of Heroes of the Storm? Probably not. But where are we going?

Well, of course none of us know. But we can speculate. Where do you think we're going next?
