Sony has announced it will be holding a special PlayStation VR event at the Game Developers Conference next month. Many industry experts reckon the company will reveal the pricing and release date for the PlayStation VR headset -- a rival to Oculus Rift and HTC Vive. The event will take place on March 15 in San Francisco -- the same day that Apple's rumoured iPhone 5se announcement could take place. The PlayStation VR headset has been under construction for the last two years.
