Prototype Valve VR headset leaked: HTC Vive challenger confirmed?

Leaked images have revealed the Valve VR headset, with the device subsequently confirmed to be in development as a possible challenger to the HTC Vive.The images of what appeared to be a prototype virtual reality headset were discovered on Imgur by Redditor 2flock. Valve teamed up with HTC to launch the Vive in 2016 and the Vive Pro this year, but the printed circuit boards (PCBs) featuring the Valve logo hint that the reclusive company is working on its own VR headset.A closer look at the images reveal what appear to be integrated SteamVR sensors, which are also found in the HTC Vive, Vive Pro, and Pimax 8K. There also appears to be a USB port in a slot in front, which may possibly be used for add-ons.There are also two visible cameras and integrated headphones, with the lenses appearing to be larger than the HTC Vive for a larger field of view.
