I believe Xbox, Playstation etc will all be full VR platforms in no time. All new games are going to be VR after 2016. Simply because after playing five minutes in VR, flat screen games are lame, games from the ancient past.
So, as a wild speculation, it could be that with Microsoft Oculus shifts to consoles and VIVE conquers the PC markets with Steam.. ? If Sony fails with their own HMD, maybe Playstation suffers the faith of Nintendo?
