It's not like Call of Duty, where past Sony agreements could prevent that from making it available to Diablo 4 Gold buy Game Pass for a few years, it's unlikely that anything like that applies to Diablo as well, which would be a massive win for Microsoft.
I'm not interested in the notion that Diablo 4 is going to be an Xbox exclusive, due to the fact that I believe that A) Microsoft wants those alt-platform sales, and B) I'm not convinced that this acquisition will be done by the time that this game comes out anyway. But never say never, I suppose.
Diablo Immortal, Blizzard's mobile-focused entry in its action-RPG franchise has now made more than $300 million in revenue according to reports. In reference to this, the massively loved Raid: Shadow Legends made record profits in 2021, up to $370 million. This means that Diablo Immortal, which only released this summer, well ahead of the trend, at the very least financially.
At the time of its release, Diablo Immortal was the subject of harsh criticism as well as fan backlash. Even though many reviews described satisfying and fun gameplay consistent to the Diablo series The players were outraged over the game's shocking microtransaction-based economy and went to review bombing Diablo Immortal in protest.
Blizzard Entertainment president, Mike Ybarra, defended the microtransactions by saying that the majority of players pay nothing even. This didn't calm angry players however, who are confronted with a system which aggressively demands that they use real money or have to Diablo IV Gold endure a huge grind.
