August 2nd is the trial date, but both companies say, "Withdrawal from adjudication is not only mandatory but in the public interest."
"We're optimistic about getting this done, and excited about bringing more games to more players everywhere," says Xbox boss Phil Spencer.
The UK's Competition Appeal Tribunal was originally set to begin proceedings around Microsoft's appeal later this month.
In recently submitted court documents, Microsoft stated that Nintendo has "a contractual right to obtain Activision content post-merger, including Call of Duty."
Other Activision franchises like Overwatch, Diablo, Crash Bandicoot, and more aren't guaranteed to release for PlayStation in the future.
"We look forward to a future where players globally have more choice to play their favorite games," says Xbox boss Phil Spencer.
Earlier this year, Microsoft signed a "binding" 10-year agreement with Nintendo to bring Call of Duty games to its platforms.
The US Federal Trade Commission's appeal against the verdict by Judge Corley in its trial against Microsoft has been denied by the Ninth Circuit Court of Appeals.
However, the CMA says it "aims to discharge its duty as soon as possible and in advance of this date."
The FTC was recently denied an injunction against the proposed acquisition, while Microsoft has also begun negotiating with the CMA.
The FTC hopes to use its appeal to try and file an injunction against Microsoft's acquisition of Activision Blizzard until a trial slated for August.
The CMA also states that if Microsoft chooses to suggest a restructured deal during negotiations, it could still "lead to a new merger investigation."
The FTC has until Friday to appeal against the recent ruling, which denied an injunction against Microsoft's proposed acquisition of Activision Blizzard.
Microsoft's Brad Smith said it's looking at how to modify the deal and address "concerns in a way acceptable to the CMA."
Microsoft is now free to close the deal ahead of the July 18th deadline but must solve its issues with the CMA in the UK.
The update brings with it Starlight, Black Noir, and Homelander from The Boys, along with other features such as playing battle royale on the Vondel map and a new Gulag.
Microsoft made the decision that all ZeniMax games would be Xbox exclusive back in 2021.
"It’s probably the second most successful video game system of all time, so it was a bad decision on my part," says Bobby Kotick.
Activision only agreed to bring Call of Duty games to Xbox Series X/S after Microsoft agreed to an 80/20 revenue split.
PlayStation CEO Jim Ryan wrote in an internal email in January 2022 that he believes Microsoft's bid to acquire Activision is "not an Xbox exclusivity play at all."
