Today, Phil Spencer, head of Microsoft's Xbox division, announced on TwitterMicrosoft has signed a 10-year deal with cloud gaming services provider Ubitus, which promises to bring Xbox PC games and Activision Blizzard's titles, including Call of Duty, to the platform after its acquisition of Activision Blizzard is completed.

Microsoft has signed similar "ten-year agreements" with Nintendo, Nvidia, Boosteroid and Ubitus, promising it will release Call of Duty and other games on corresponding platforms simultaneously after the acquisition.

With respect to the above agreement,Phil Spencer says the promise is to give players more choice; Microsoft President Brad Smith later added that this ensures that people around the world can play games, including Call of Duty.

It's worth noting that Microsoft offered SONY a similar deal, promising to keep the Call of Duty series on PS5 and other platforms at the same time after the acquisition, and allowing SONY to add the games to its PS Plus membership game library.

But as of this paper,SONY did not sign the deal, nor did it make any concessions to Microsoft's acquisition of Activision Blizzard, remaining staunchly opposed to the deal going forward.
