dryriver writes: Sony is preparing to reveal the final piece of its PS4 hardware strategy at TGS by showcasing a PlayStation-branded virtual reality head-mounted display, CVG has learned. It originally intended to reveal the headset at Gamescom but plans fell through at the eleventh hour. The company is currently weighing up whether the PS4 device should be pitched as a key differentiator for the console or a non-essential add-on. The matter has been slightly complicated, but not derailed, by the growing industry support for Oculus Rift. Sony's device will be a categorical rival to Oculus, and for months there have been rumours suggesting the two companies are seeking a partnership. A games developer familiar with Sony's plans, who wished to remain anonymous, told CVG that Evolution Studios is currently working with the device to simulate a cockpit view on its PS4 title Drive Club. Another developer claimed the virtual reality headset resembles the 3D headset that Sony first revealed in January 2011. The head-mounted display will be available separately, like with the new PlayStation Eye, in order to keep the baseline PS4 price as low as possible.
