Diablo III and all its predecessors have a fixed camera with an isometric view. We can zoom in, but basically that's it. Monstrousd3 messed a bit with the camera angles and made a short clip showing how the game would look from a different perspective, similar to World of Warcraft's.
It certainly looks a bit strange. There's something cool in how Diablo attacks us at the end of the video, but there's also a reason the Diablo games don't have this sort of third person view and WASD controls.
