Its bad news.
Microsoft basically had a choice of making more games (good for consumer), or buying up existing IP via buying a publisher (bad for consumers).
This ultimately means less games, we going further down that narrowing cone.
Too many publishers deciding they prefer to keep releasing games as a service, and sticking to known successful brands instead of new ideas and new content.
I have observed a lot of the third party exclusivity deals for PS5 now dont exclude PC, typically they timed exclusive PS5 only, then make it to PC, but never to Xbox.
