That would be the extra that xbox lacks, i mean, the windows 10 core and x86 architecture is already there, and with Series X you have now the power to run PC games at acceptable speed and graphics so it's just a matter of adapting the system to allow that and the console would be much more...
Seems like XSX uses the same base OS as XBOne for now so unless they decided to remove for some weird reason until launch they will probably keep it. Just hope they bump up the allowed hardware usage in dev mode, would be really cool to see Dolphin running on 4K at decent speds on Xbox
Of course, because bugs that doesn't allow players to complete story are super normal and expected in games, right? Well, i will just accept that i can't finish the game i paid for and go play Solitaire then.
