Microsoft's stance now is to move as much as it can to GamePass. It opens the accessibility block for gamers who never played these titles and want to start playing them. Moreover, we're still going to see Bethesda doing titles for other consoles (PS5) with Deathloop and Ghost:Tokyo because they clearly said that both those were in development before the acquisition. They will port them over at a later date.
I think this is good for the gaming community because now you have a company with a rich history of cross-platform gaming going to a service-based delivery system backed by another company that has proven it works. I think PC gamers have so much to be happy about now with the plethora of choices at hand in Steam, GamePass, etc that this is the future of gaming. Sony and Nintendo don't think so and have curiously stayed away from this but we'll see them make the move too once they start coming to terms with how they sell and market their flagship games (none of them are particularly good multi-player but the single-player is of elite quality).
