No chance. COD has consistently been a huge money maker on PS and Vanguard was #1 last year. They would lose out on way too much revenue, not to mention that massive negative sentiment that would bring towards Xbox and big game / console manufacturers. I think certain games like Halo and maybe some Bethesda will stay (ones that have previously been exclusive). But acquiring a AAA company and then cutting off half of your customer base seems like a big mistep.

Console exclusivity is no longer the driving force for revenue, that's GamePass.

Selling full versions everywhere else is good business, we saw that from both Microsoft and Sony making more PC ports - and for Xbox it is yet another driver into their subscription model.
