CVG states that Sony originally intended to present a PlayStation-branded virtual reality head-mounted display at GamesCom 2013, but finally they decided to postpone the public presentation. Some sources are telling us, though, that this device perhaps was presented at a closed door event that Sony held in order to present some kind of new hardware.
Eurogamer goes beyond and states that the hardware will be finally presented at Tokyo Game Show 2013.
This VR device would be intimately linked with PlayStation 4, in fact the device has been demonstrated with Evolution Studios’ Playstation 4 racer DriveClub, with players able to look around the cockpit of a car. This VR headset would work very similar to Oculus Rift.
