Not having a pro version on its own is another sign of the console business being wound down imo. ActiBlizz would likely complete the transition to a true software and subs company.
They will likely keep xCloud running and try to grow that into a sub model on your devices ala Netflix + 3P publishing biz for PC/Nintendo/Sony/Whoever and it will likely be a far more profitable path for them.
There's no profit in Xbox as a strict console ecosystem (in fact, MS's entire gaming division likely doesn't make a profit right now), otherwise they would be announcing it even if it's small, a win like that would definitely be used as a PR point in their earnings calls (just like we always used to hear about the series console sales in the beginning of this gen), instead we're getting stuff about hours played without any actual growth in $$$ received by the biz vs last year.
The reason they are getting a 69bn warchest is because even if they pull out of the console game, ActiBlizz will still grant them great power as a 3rd party publisher, especially if they want Sony and Nintendo to accept gamepass being a thing on their ecosystems.
