The rest of this article below is from 2012 and remains unedited since the Rumor was confirmed to be true at the later PS4 Reveal Show:
RealGamerNewz reported not too long ago that although Blizzard Entertainment was actively seeking a console solution to their PC exclusive title Diablo III (which released to much fanfare last month).
However, at the time it appeared that the Xbox 360 version of the game could have been holding this undertaking back in a big way. Further rumors speculated that Blizzard might be looking at the option of canceling the console version of the game, though a PS3 version has recently been revealed.
Aaron Alexander of Planet PlayStation reports on the late-breaking rumor just discovered due to a german listing for the game on PlayStation 3 to be released this year. As Aaron notes, Sony has been known for its open online network PlayStation Network.
Rather than paying Blizzard, Sony may be harnessing their ability to allow developers and publishers to take control of their intellectual properties for custom solutions such as user-generated content, cross-platform play, dedicated servers, and even SteamWorks support from Valve.
