VR 'doesn't count' for many, many reasons. It's disingenuous to say that VR should 'just work' on current-gen consoles. Neither of them was designed for it to begin with. Sony is shoehorning it onto their platform and MS is drawing a line in the sand. Two different approaches, both of which are not simply 'PLUG UR OCULUS INTO UR CONSOLE AND IT WORKS!!'
The problem, though, is that Microsoft simultaneously claimed 'no Scorpio exclusives' and that VR would be Scorpio-only. That, not surprisingly, probably confused a lot of people.
