I think the next ES game will be located in Elsweyr, simply because there's a lot of talk in Skyrim about Elsweyr. The way that the Khajit "outcasts" talk about Elsweyr outside of cities made me pretty assured about this.
Note: I am by no means a Khajit fan

But it would be interesting to see all those "cities so huge that deserts have swallowed them" and all the desert and ancient culture and all that.
Do you guys think i'm right and would you be happy if the next Elder Scrolls was in Elsweyr?
