There seems to be this weird perception that Scorpio is "just" an upgraded Xbone, and THEN they'll release the Xbox 2 which will be the real brand new next gen thing and yadda yadda
The Xbone is the Xbone, Scorpio will be a significantly upgraded Xbone, Scorpio II will be a significantly upgraded Scorpio, Scorpio III will be a significantly upgraded Scorpio II and so on.
Xbone accessories and their games will be usable on an Xbox system as long as MS is in the console industry, theres no singular generation anymore (for them)
Hell, if they somehow work out OG Xbox emulation then youve got barely any generational gaps in their entire legacy of consoles, the only things missing would be OG Xbox online play, OG Xbox accessories and 360 accessories
