Well, we were wrong about "The Dark Below" being a D3 Exp. I admit i'm a bit more exctited about the "special announcement" for Gamescom after this news, but i'm still on the defence, i won't let hype take control of me.
I think it's a fetish. They basically explored every act from d2 in d3 (wilderness, desert, highlands) so the kurast jungles would make sense as a new setting to explore once again. Looking forward to more info on this
