Blizzard has confirmed that Diablo IV will in-fact be online only. Thanks Blue's.
“Sanctuary has been a home to Diablo players for more than 20 years, and it’s with our own deep passion for the series and a deep appreciation of the community that we announce Diablo IV today,” said J. Allen Brack, president of Blizzard Entertainment. “We’re excited to be returning to the dark, quintessential Diablo gameplay that players love while expanding the world and story in new ways, and we can’t wait for more people to be able to experience it.”
