Microsoft has a near monopoly on the OS of computers, yet they have struggled to catch Apple in the phone and tablet sectors with their Windows equivalents. I don't see them suddenly convincing people to buy an Xbox because of Windows 10, especially at $399. People can rationalize a phone because it does so much and the games are a bonus. A gaming console is for games with the applications and all being the bonus.
As for sales, with Sony having a greater global presence I'd be surprised if the X1 in 5-7 years is doing as well comparatively to the PS4 as it is now. The marathon favors Sony.
