I can pretty much guarantee that if we decide to do a console version that we will look to support a pad on the PCSource:
From a thread praising the arrival of D3 on PS3:
02/25/2013 02:59 PMPosted by VaeflareVaeflare, do you have an ETA on when we can expect some developer discussion on how the console version of Diablo 3 will affect future PC design? i.e. Adding controller support to the PC, clarification whether we can expect an offline feature similar to the console version, cross-platform play, etc
While we think cross-platform play would be awesome, there are currently no plans to allow connectivity between PlayStation Network and Battle.net (this is pretty standard for most games that have PC and console support). As a result, the characters on your Battle.net account and PlayStation account will also remain separate.
In terms of allowing an analog controller hookup for the PC, we don’t have any plans for that kind of support right now. Similarly, since Diablo III for console was designed with a controller in mind, the PlayStation version of Diablo III will not support USB mice or keyboards.
Why the 180? Why a guarantee before you sold people the PC version and "we don't have any plans for that kind of support" now that you want to sell us a second version of the same game? I understand that people that want to use a controller for D3 are probably in the minority, but we do exist. Why did Jay Wilson lie?
