The D3 control scheme (on PC) is hardly changed from D2, and D1 prior to that, in that you still point, click, and you have Action Bar quick-keys which can be mapped to whatever you want on the keyboard (along with every other command). Diablo 1, 2, & 3 were all developed first and foremost for the PC.
Saying Diablo 3 was developed as a console game is not an educated statement. D3’s console gameplay/control experience doesn’t hold a candle to D3’s PC controls.
