I doubt Microsoft would make a handheld that was "open" like the Steam Deck. They'd follow the console business model of only allowing software from the Microsoft store and it would likely not sell very well. It would be Windows Phone all over again.

True. But Nintendo has sold very well from their proprietary handheld device and its store. So they probably think they can. Maybe they can. They already have a great UI in Xbox and a great library of games that will run. They might not need anything else to make it.
