In 2026 we should be getting Windows on a Xbox console with the Xbox skinned version of windows. This would be a direct competitor to that since most PC gamers have the majority of their game library on steam.
Isn't that what the ROG Xbox Ally devices have? At least that's what it looked like to me. Something like a SteamOS's gaming mode counterpart for Windows.
From what I could tell, the ROG Xbox device was just Windows desktop mode with a full screen "Xbox" application open, which you can minimise and see the normal desktop behind it.
