The FTC, during the Preliminary Injunction trial at the end of last month, made total fools of themselves in how they went about trying to block this. There well may be legitimate antitrust/anticompetitive reasons to block this, but they just did not go about it the right way. They came off looking more like defense attorneys for Sony rather than a consumer watchdog group.
And the CMA in UK is blocking it on the grounds of...cloud gaming being a separate market? lol It really isn't, and I believe that all the relevant cloud gaming companies have said as such. Cloud gaming is, as it currently stands, in such an infancy that no one knows how it'll shape over the next decade+.
So yeah, I expect MS will close it, and maybe after this they'll actually start getting some of their own published games released and showing us gamers the fruits of these acquisitions.
I NEVER expected CoD to become an exclusive. They'll slap it on Game Pass as a Day 1 release to try and entice Sony-only gamers over, but they'll keep publishing it on PlayStation because to do otherwise they'll be foregoing all of that revenue.
