It's just a patent folks, it means fuck all for Xbox VR plans or lack of. Their R&D team, probably working on hololens, came up with this and for all we know it might just be patented to lock it away.
Which is a dick move.... stuff like that shouldnt be allowed.
Its nuts you can patent something you never even want to try to make a product out of.
