Apparently it has audio speakers that work in a 3D sort of way, also glasses can apparently be worn with it
There are lightbars on the goggles which will also work similarly to PS Move and the DS4
People will apparently be able to test out the goggles in a number of demos at GDC too!
Apparently its wired at the moment, though they are looking into making it wireless for final release.
Will only work for PS4 now, but they're not ruling out PC for the future.
No word on price, though that was to be expected as it isn't finalised.
