Diablo 2 producers and former Blizzard employee Mark Kern said the reveal of Diablo Immortal is an example of Blizzard "not understanding gamers anymore".
The community has been on a wild rampage regarding Diablo Immortal, but the company is betting that the game will be a big hit and some gaming sites had nothing but praise regarding the demo.
As for the reason for the delayed reveal, they seem to be perfectly reasonable: the design of the game has changed multiple times over the last few years and Blizzard still aren't sure they've locked things down enough to announce it.
The opening ceremony for this year's BlizzCon concluded with an announcement for Diablo Immortal, a new mobile-only Diablo set between the second and third games. For most of the weekend, Diablo fans raged online as a result, expressing their anger on YouTube and various forums. As it turns out, Kotaku has learned, Blizzard had originally planned to tease Diablo 4, but pulled those plans at the last minute.
Yesterday's report revealed that Blizzard recorded a video in which co-founder Allen Adham talked about a new Diablo game.
Activision Blizzard and NetEase didn't immediately respond to requests for comment. According to sources who spoke to Kotaku, Blizzard had meant to tease Diablo IV, which is indeed in development, but decided at the last minute they weren't yet ready to commit. In the face of this controversy, as Blizzard faces a marketing crisis, one upcoming game has already attempted to appeal to frustrated Diablo fans. "We do continue to have different teams working on multiple unannounced Diablo projects, and we look forward to announcing when the time is right".
The announcement of Diablo Immortal at BlizzCon went about as badly as it could have. But then fans quickly proved themselves to be that messy bitch who hurls things at their significant other because how dare Blizzard show up with a pearl necklace when it knew they were waiting for a diamond ring.
Furthermore, Blizzard has learned tremendously from Diablo III's launch woes and has also learned how to properly monetize its live service games for the long run.
