Random bits of information seem to be pointing at a Diablo-related announcement at Blizzcon 2016.
First up was YouTuber Rhykker, who took a look at the Blizzcon 2016 goodie bag, which includes a full set of Diablo-themed dice. A normal four-sided die has four sides of three numbers each and when the die lies flat, the same number should be on the bottom. For the D4 in the Diablo set, one side reads 1-1-4, thus making the dice unusable. Rhykker and others believe this D4 is representative of "Diablo 4" with the 1-1-4 representing November 4, which is when Blizzcon 2016 begins.
Second came the tweets from former Diablo developers David Brevik and Bill Roper. The first set of tweets involved Bervik noting that he was visiting the Blizzard offices on October 6, and Bill Roper doing the same a day later.
"For 20 years, Diablo-like games have evolved and surprised us. I'm proud to be the adviser for the game that pushes this genre to new heights," Brevik tweeted on October 15.
Brevik founded Blizzard North, becoming the senior designer behind Diablo and the project lead for Diablo II. Bill Roper is a Blizzard veteran who was the producer on the first Diablo and a senior producer on Diablo II. Both men could be brought in to advise on a remaster of the older Diablo titles, but Brevik's later tweet seems to point towards a brand new title in the series.
Blizzard was also hiring for a game director for an unannounced Diablo project this summer. The original listing wanted someone who would "lead the Diablo series into the future". This would point to a development announcement, not a full gameplay one.
So there could be new Diablo coming in some form, whether that's a sequel or another expansion for Diablo III. You looking forward to it?
