Probably the most interesting piece of new VR technology to come out of the GDC 2016 was the Sulon Q reveal; The very first wear-and-play VR and AR device that works perfectly well without the need for any external hardware. The device is powered by an AMD processor and graphics card, and makes use of Windows 10, although it is not clear whether you'll be able to use other operating systems, too. As the details for this device are very limited, speculation ensues.
With absolutely no information in this area, the most we can tell you is that this device will very likely be released before the Microsoft and Google devices and would likely be considerably cheaper. If you were to use previous trends, and factor in the advances in technology, the device should be released in about a year, likely in Q4 2017. This is entirely guess-work, albeit educated guess-work.
The device's biggest selling point is the fact that it doesn't come with any wiring or tethering. You'll probably get some connectors to project your screen on to a display if you choose to, but other than that and some chargers, there shouldn't be much else you'll need.
Also of interest is the fact that Sulon Q seems to work without an extrernal controller. How well this will work however, and how true it is, remains to be seen.
The Sulon Q uses the AMD FX-8800P processor and Radeon R7 Graphics, has a 2560x1440 OLED display and 110° field of view. The refresh rate is unknown (Very likely at least 120 hz)
"The full performance of 4 compute cores and 8 GPU cores are unlocked through a revolutionary Heterogeneous System Architecture (HSA), enabling the cores to share memory to work together for dramatic performance and efficiency
The result is a solution that is optimized for modern workloads and media formats, capable of driving the latest graphics APIs including DirectX® 12 and Vulkan™, and able to render stunning videogame console-quality visuals... The Sulon Q™ headset also integrates AMD’s LiquidVR technologies to help ensure smooth and responsive VR and AR experiences."
Sulon Q's superiority to all contenders is unquestionable on paper. However, with no real information on the release date, price, exact features, and partnership with an actual game database/studio, there is a very large question mark on its capability in reality (or virtual reality). Still, something to look forward to!
