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.

At the recent Game Developer Conference and Mobile World Congress events, Valve had a demo for HTC's Vive VR system that was based in the Portal universe. The headset is combined with two controllers, one for each hand, which sound like a cross between Valve's Steam Controller and the Razer Hydra.
When HTC briefed journalists about the technology, they brought a few examples for use with their prototype. C|Net described three: a little demo where you could paint with the controllers in a virtual space, an aquarium where you stand on a sunken pirate ship and can look at a gigantic blue whale float overhead, and a Portal-based demo that is embedded above. I also found “The Gallery” demo online, but I am not sure where it was presented (if anywhere).
Beyond VR, the Source 2 engine, which powers the Portal experience, looks good. The devices looked very intricate and full of detail. Granted, it is a lot easier to control performance when you are dealing with tight corridors or isolated rooms. The lighting also seems spot on, although it is hard to tell whether this capability is dynamic or precomputed.
The HTC Vive developer kit is coming soon, before a consumer launch in the Autumn.

Hardware/Software Picks of the Week:
Jeremy: Um, I don’t know, SteamOS sales I guess?
As GDC progresses here in San Francisco, AMD took the wraps off of a new SDK for game developers to use to improve experiences with virtual reality (VR) headsets. Called LiquidVR, the goal is provide a smooth and stutter free VR experience that is universal across all headset hardware and to keep the wearer, be it a gamer or professional user, immersed.
AMD's CTO of Graphics, Raja Koduri spoke with us about the three primary tenets of the LiquidVR initiative. The 'three Cs' as it is being called are Comfort, Compatibility and Compelling Content. Ignoring the fact that we have four C's in that phrase, the premise is straight forward. Comfortable use of VR means there is little to no issues with neusea and that can be fixed with ultra-low latency between motion (of your head) and photons (hitting your eyes). For compatibility, AMD would like to assure that all VR headsets are treated equally and all provide the best experience. Oculus, HTC and others should operate in a simple, plug-and-play style. Finally, the content story is easy to grasp with a focus on solid games and software to utilize VR but AMD also wants to ensure that the rendering is scalable across different hardware and multiple GPUs.
To address these tenets AMD has built four technologies into LiquidVR: late data latching, asynchronous shaders, affinity multi-GPU, and direct-to-display.
The idea behind late data latching is to get the absolute most recent raw data from the VR engine to the users eyes. This means that rather than asking for the head position of a gamer at the beginning of a render job, LiquidVR will allow the game to ask for it at the end of the rendering pipeline, which might seem counter-intuitive. Late latch means the users head movement is tracked until the end of the frame render rather until just the beginning, saving potentially 5-10ms of delay.

Mobile World Congress (MWC) and Game Developers Conference (GDC) severely overlap this year, and not just in dates apparently. HTC just announced the Vive VR headset at MWC, which was developed alongside Valve. The developer edition will contain two 1200x1080 displays with a 90Hz refresh rate, and it will launch this spring. The consumer edition will launch this holiday. They made sure to underline 2015, so you know they're serious. Want more information? Well that will be for Valve to discuss at GDC.
The confusing part: why is this not partnered with Oculus? When Michael Abrash left Valve to go there, I assumed that it was Valve shedding its research to Facebook's subsidiary and letting them take the hit. Now, honestly, it seems like Facebook just poached Abrash, Valve said “oh well”, and the two companies kept to their respective research. Who knows? Maybe that is not the case. We might find out more at GDC, but you would expect that Oculus would be mentioned if they had any involvement at all.
Valve will host an event on the second official day of GDC, March 3rd at 3pm. In other words, Valve will make an announcement on 3/3 @ 3. Could it involve Left 4 Dead 3? Portal 3? Will they pull a Crytek and name their engine Source 3? Are they just trolling absolutely everyone? Will it have something to do with NVIDIA's March 3rd announcement? Do you honestly think I have any non-speculative information about this? No. No I don't. There, I answered one of those questions.
