Blizzard maintains that it had never meant to talk about Diablo 4 at BlizzCon and that no announcements were pulled from the show.
Blizzard has not yet announced if Diablo Immortal will be a free or a paid title, though Blizzard developing the title with free-to-play veteran NetEase might offer a clue.
"Diablo was supposed to be Blizzard's first shot on goal into the big global mobile game market", Jefferies analyst Timothy O'Shea wrote noting the criticism from Blizzard's PC fanbase.
Activision Blizzard held its annual BlizzCon conference over the weekend, and many gamers hoped that the next major entry in the Diablo franchise would be part of the event.
Diablo IV is in development and an official confirmation was supposed to happen at BlizzCon 2018, sources tell Kotaku's Jason Schreier. Apparently, Diablo 4 is in development, but the team wasn't ready to commit to an announcement as the game has changed "drastically" over the past four years and may continue to evolve. There was much criticism with many saying that the Diablo: Immortal reveal should have been followed by confirmation that Blizzard is working on Diablo 4, a strategy adopted by Bethesda when it announced Elder Scrolls: Blades before confirming The Elder Scrolls VI. The fan backlash against the game was strong enough that Activision Blizzard's stock price was impacted. "These are very exciting times-we now have multiple teams working on different Diablo projects and we can't wait to tell you all about them. when the time is right", the company said. Kotaku's sources say the presentation was supposed to end with a video featuring Blizzard co-founder Allen Adham solidifying plans for a Diablo 4 while assuaging fans wanting to see footage. Since then, new updates have been scarce, with an occasional new content patch arriving sporadically and a Necromancer character pack hitting in 2017.
"Since I was producer on Diablo 2, a lot of people have been asking for my thoughts on the whole 'Diablo Immortal' fiasco".
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. One of them is the game that fans are waiting for, and it was almost announced last week.
