Oculus has sold about 25,000 DK2 Rift headsets, reaching a total of 85,000 developer kits sold so far.
Gamasutra shared the figures on Monday which reveal healthy interest in the VR company's latest test version. DK2 incorporates a high-resoltion, low-persistence OLED display and head tracking with a USB camera accessory. It costs $350 with delivery estimated to begin in June.
Though DK2 brings Oculus closer to its goals for a consumer release, the company says it still needs more refinement before it's ready for large-scale consumer release.
Facebook announced in March that it had purchased Oculus Rift for $2 billion in total assets. Oculus CTO John Carmack has responded to criticism, saying the VR start-up now has the resources it needs to "make it happen".
Microsoft said in early April that it's continuing to explore the possibility of entering the virtual reality market.
