Maybe they see this as the prefect time to go after VR,MR & AR Gaming & having a camera on your head as part of the headset is a easy way to see what the player is seeing in the real world so they can use it in the game. if you have the PlayStation Eye go into EyeCreate & place the PS-Eye on top of your head stick your hands out in front of you while looking at the TV you will quickly realize that this is the way that the EyeToy \EyePet & other AR games should have been played in First Person View. the only problem being that the TV will be picked up by the camera creating a endless loop but that's easily fixed by using AR to make your TV a game menu or something when it's picked up by the camera.
Also think about the code name for the PlayStation 4 it's Orbis.
"Orbis in English
circle, orb, ring, disk, orbit, coil/ round / rotation."
To me that goes perfect with the idea of having the camera on your head & placing the game around you.
look at the controller it's an AR Marker.
I'm in my room now with the PlayStation Eye on top of my head looking around my room & it's actually scary to think about someone making a scary game with stuff popping up in your room & the lights blink on the TV & switch to the camera that's pointing at you & it shows something standing behind you all while using 3D Sound .
