Diablo III is for real

[nobbie]

No, I'd say those areas are grey to represent the snowy environs. There are alot of places on that map in bright color which won't show in D3: for example, Skovos, which they specifically mentioned during the lore panel.

Although, an expansion set in in the Chinese-sounding Xiansai would be fine with me. :P

Might well be, I didn't see all panels during the WWI. But whatever, if they build the whole world of Sanctuary in 3D (like Azeroth in WoW), I expect some fantastic regions and atmosphere coming in Lut Gholein (incl. the sewers with Radament) and the vast jungle with the Temple of Kurast:)
