One can dream. Honestly, Sunset Overdrive was the only Xbox One exclusive that I've always been interested in. Just don't want to buy an Xbox just for one game.
Kidding of course. Entirely up to Microsoft if that happens (IIRC the IP belongs to Insomniac while the rights to the game belong to Microsoft), would love to see it become a thing alongside Xbox One X enhancements.
Insomniac owns the IP I believe, so unless they need Microsoft's approval to port the game then it would probably come down to money. Sunset Overdrive is three years old now and unless you're sure it's going to sell there's no reason to spend the money and do the work.
