Blizzard Entertainment community manager Micah Whipple has confirmed via Twitter that Diablo III will be coming to consoles. Whipple broke the news via a response to a user asking him to confirm or deny the project.
No word on what platforms it will release on, but it's a safe to assume PS3 and Xbox 360 due to the plurality of t word "consoles". Now that the cat is out of the bag, expect a proper announcement and details in the near future.
