Diablo Anniversary Event Returning, No Franchise Announcements at BlizzCon

If you were hoping for a Diablo IV announcement or at least a Diablo II: Remastered reveal at this year's BlizzCon event, you'll be disappointed to read this forum thread by community manager Nevalistis that tempers those expectations here and now. There will be some sort of in-game reward for attendees, there's talk that the Tristram anniversary event will be returning in January, and there will be Diablo discussion panels, but other than that, there won't be a whole lot to get excited about:
BlizzCon draws near, and we wanted to give you an update about Diablo’s presence at the show. Last year at BlizzCon, we kicked off Diablo’s 20th anniversary by announcing the old-school cathedral dungeon (if you missed that the first time around, it’s coming back in January) and unveiling Rise of the Necromancer. This year, we want to give you a heads-up that while Diablo will be on the show floor, we won’t be making any new Diablo announcements. There will be a time for that at some point in the future, but that time is not now.

However, in addition to the special BlizzCon Diablo III in-game reward, we’ll also have Diablo panels for attendees and Virtual Ticket holders, and, as always, we look forward to a weekend filled with fun and revelry with the heroes who call Sanctuary home.

Patch 2.6.1 is on the horizon. Looking beyond that, we’re hard at work on the future of Diablo and exploring what’s next for the franchise. Please be patient. Our passion for Sanctuary burns as bright as the High Heavens and as hot as the Burning Hells—and we’re excited to hunker down and get working!

Until next time,
The Diablo Development Team
