Yeah, I do wonder if Sony will pull an Epic Game Store and pull Sunset Overdrive off the Microsoft Store and/or Gamepass. Although I don't think they can as I "think" MS owns the IP for that, but I'm not entirely sure.
That's one thing I like about Microsoft's acquisitions. Unlike Epic, they allow games that were in development prior to signing with Microsoft to be available on all platforms and stores they were on or were planned to be on if the game hasn't been released yet. Minecraft, Wasteland 2, Bard's Tale 4, Hellblade, The Outer Worlds, etc...
They could have easily made Minecraft a platform exclusive if they wanted to. But they thought of all the existing customers and instead decided to support all platforms...even years after the aquisition. Then again, the blowback of negative press would have been enormous, something that Epic doesn't care about.
