Diablo 3 on the PS3 seems to have the same amount of hotkeys for skills, as Diablo 3 on the PC has.
Diablo 3 really feels like it was originally built for PC, due to the simplified structure of skills and hotkeys.
I don't know whether or not it's because of patch updates or because it's on another console, but Diablo 3 on the PS3 feels very easy.
When I fought Belial in Act 2 on PC, I couldn't beat him alone and I had to do it with the help of my friend (a Barbarian). When I played on PS3, well... I took down Belial solo in under thirty seconds.
