Interesting data. It's very uncomfortable to watch that sociopathic monster FaceBook taking over.
Apple may be the next mover. But that would almost certainly be marketed as an iPhone accessory (i.e., must be connected to the phone for it to work) and also almost certainly AR, not VR, just because all-encompassing VR is so isolating. But Iphones and ipads have had (off-head) AR capabilities for a while now and things have barely moved past rather desperate-feeling "look, isn't this cool?" tech demos, to the point that few people even know their phones can do it at all.
I haven't found myself a fan of current VR quality, but mixing in my real-life wheel and other controls would be nice. Better cameras are needed for that than are currently equipped for position sensing, obviously.
