Diablo III is for real

[FoxBat]

Note that the game itself is also fully 3-dimensional now: dungeons will be randomly generated in 3D(!), and monsters as well as other moving objects can move and attack in any direction (x,y,z). This is a big step forward, and I'm convinced the gameplay will be as fantastic as the look.

Where do you get that idea? Despite the sweeping vistas, the game still look like it plays on an essentially flat plane.
