Blizzard community manager Bashiok confirmed over Twitter that there is indeed a Diablo 3 console version in the works stating,
Yup. Josh Mosqueira is lead designer for the Diablo console project.
We don’t yet know what consoles are included, but my guess would be Xbox 360 and PS3. I don’t know why, but I just don’t see D3 being made for the Wii.
Now the questions remains, will Blizzard hold out the PC release to line up with consoles? My July 1st release date prediction is looking better and better :)
