If the CMA's ruling is not reversed, Microsoft may relocate its operations to mainland Europe and serve the UK through a distributor. Microsoft has since appealed the decision. The merger was blocked in April by the UK's Competition and Markets Authority (CMA), which claimed it would give Microsoft too much control over the cloud gaming market.

These major expansions will not only add new gameplay content but will also expand on the game's story, which will also be developed via free seasonal updates as part of the title's live-service structure. According to general manager Rod Fergusson, Diablo IV will be supported 'for years to come,' with Blizzard already working on two expansions for the game.Diablo IV's predecessor, Diablo III, sold 3.5 million copies immediately after release, making it the fastest-selling PC game of all time at the time. The previous record was set by World of Warcraft's Shadowlands expansion, which sold 3.7 million units on its first day of release. It not only revealed the impressive playtime figures, but it also claimed that it is the fastest-selling game it has ever released, though no data was provided to support this claim.The studio put the figure in context, stating that it is roughly a single person 'playing 24 hours a day since the beginning of human civilization.' So far, the game has been well received by players, who have praised it for its satisfying combat and gameplay loop. Blizzard revealed in a new press release that since the game's early access period began on June 1 for Deluxe and Ultimate edition owners, players have accumulated more than 93 million hours of playtime, equivalent to more than 10,000 years.

Blizzard has stated that the game is now the fastest-selling game in the company's history based on the number of hours players have put into the game since its June 6 release, with an early access period beginning four days prior.
