Update: It does look as though this is the Diablo III reveal. See here.
No more speculation. Speaking at Paris GDC, Rob Pardo’s admitted that there’s going to be some kind of proper game announcement at the Blizzard Invitational in Paris this weekend.
“So you want me to announce the game before our announcement?” he said. “No offense, but I think there’s like 300 people here, and I’ll be ripped apart by 8000 people there [at the Invitational] if I pre-announce it – but it’s going to be really exciting. I think everybody here will be really excited about the announcement.”
