A grain of salt is needed for this one. Users on Reddit claim to have found a pair of renders, one of the headset and one of the controllers, for the HTC Vive VR system. They also have a screenshot of the page, although the first words you see are “This Is Real,” which are the most sketchy, ironic, and unfortunate words to be greeted with in a product leak.
The current HTC Vive prototype looks like a rough version of this. There are some significant differences, though. My major concern is at the front of the headset. You can clearly see a front-facing camera as well as two nubs below it, one to the bottom-left, and one to the bottom-right. If those two nubs are also cameras, then that makes a bit more sense.
If those two nubs are not cameras, then Valve would have downgraded from a two-camera system, in the original prototype, to a single camera. Valve has already claimed that the Vive will have front-facing cameras, plural, to track objects (like pets) for safety reasons. I can see them adding an extra camera, but I doubt that they would use just a single one. Two cameras allow more accurate depth tracking at low distances, which is when you risk… interacting… with the user. That sounds unlikely.
If it's three cameras? That makes sense.

The controllers are also interesting, but mostly from an aesthetic standpoint. The hexagonal plates, which apparently functioned as sensors, seem to have been changed into circular rings (if the hole goes all the way through). They retain their thumb trackpads, triggers, and a couple of buttons. It's unclear whether each controller is identical, or if there's a difference between the intended-left and intended-right models. Being a lefty, I hope not.
At roughly the same time, Cher Wang, the CEO of HTC, announced that the HTC Vive will be unveiled at CES (in January). It won't be available until around April, but we should know basically all there is to know about the system at next month's trade show. Given this timing, and that multiple users have been posting the leak seemingly independently, it sounds valid. The camera configuration, on the other hand, takes a bit away from that.
