Blizzard Entertainment has confirmed that the PlayStation 3 and PlayStation 4 versions of Diablo 3 won’t link up with Battle.net, which means no cross-platform play using your profile on the PC side. Word comes from Blizzard community manager ‘Vaeflare’ speaking on the Battle.net forums, as spotted by Shacknews.
just shame that blizzard cared more about ripping gamers of with the AH on PC version that they wanted everyone trading through it, that they never gave them the option for offline mode...oh wait it was because of piracy... pfft please
What's most important is that it may not utilize the D3 auction house which requires a Battle.net connection.
