There is no such thing as an Xbox in reality anymore.
Buzz word only being used so that suddenly the current Xbox instal-base don’t migrate to Playstation.
They would want more & more of those to stick with Windows Platforms while Sony would want more to migrate to Playstation.
Activision-Blizzard-Zenimax are the new lead M$ gaming companies & they would have released these games irrespective of the ownership change.
M$ Windows will be the lead Gaming platform & the above mentioned gaming companies will be the lead Gaming Software producers which will be available everywhere.
Think of GamePass to be soon like EAplay,Ubi+ & all once the said migration is complete.
This good news. Full slate will come now since Sony dont see MS as competition, plus with Steam store access available on Next Xbox console PC hybrid system, all Sony games will run on Xbox devices anyway.
Win win for everyone.
