Oculus VR has confirmed that it has sold 12.5 thousand units of its second developer kit for the Oculus Rift virtual reality (VR) headset, named DK2, within the first 36 hours of pre-orders opening. Company founder Palmer Luckey confirmed the news to VRFocus at last night’s VR Mixer event at the 2014 Game Developers Conference (GDC).

DK2 was revealed on Wednesday, 19th March, 2014. It was made available to pre-order straight away at the price of $350 USD. It packs numerous improvements over the original developer kit, including a 5-inch, OLED, low-latency display with low-persistence. These upgrades are said to help significantly reduce the effects of simulator sickness, which is a common issue with the original kit. There’s also the addition of extensive positional tracking that will allow users to move the headset up, down, forward, backs, left and right and have it all picked up and replicated in-game.

Oculus VR has confirmed that those 12.5 thousand orders and more will start shipping in July of this year. While DK2 includes much of what we’ll see in the eventual consumer release of the Oculus Rift, the company is yet to reveal a launch date for the much-anticipated model. VRFocus will continue to follow the progress of the Oculus Rift DK2 and report back with all the latest.
