Call of Duty and other Activision Blizzard games won't appear on Xbox Game Pass until next year. On the Official Xbox Podcast, Microsoft Gaming CEO Phil Spencer claimed that players wouldn't be seeing a big drop of those titles immediately, due to the lengthy regulatory challenges the company faced in its buyout attempt. Since it was uncertain whether the acquisition would be approved by Britain's Competition and Markets Authority (CMA) until recently, Xbox wasn't able to do the groundwork for adding the catalogue to their gaming subscription service. Ahead of the deal's closure, Activision Blizzard confirmed on Twitter that the upcoming Call of Duty: Modern Warfare III and newly-launched Diablo IV won't be coming to Game Pass soon, but Spencer's statement covers older titles as well.
