This past Friday during the BlizzCon 2018 opening ceremonies, the company announced Diablo Immortal, a new mobile take on the classic hack ‘n’ slash franchise. Reaction has been strikingly bad, with fans raging online and even directly confronting the game’s developers at BlizzCon. Even a former Diablo producer has questioned the way Blizzard revealed the game.

Well, according to Kotaku’s Jason Schreier, Blizzard originally intended to reveal something much more fan-pleasing during the BlizzCon opening ceremonies. Until the “last minute,” the plan was to follow the reveal of Diablo Immortal with the announcement that Diablo 4 was in development, but not ready to show yet. In other words, something similar to Bethesda’s Starfield and Elder Scrolls 6 E3 announcements.
