Originally, NVIDIA wanted to roll it out by Christmas but the problem is you need a 120Hz LCD display, and those aren't available yet, NVIDIA is waiting for Samsung, ViewSonic and others to release 120Hz LCD displays en masse. Furthermore, you'll also need a high-end GPU like the GeForce 8800 GT or better, GeForce 9600 GT or higher or GeForce GTX 200 series.
The kit will feature two major parts: wireless 3G goggles and an IR emitter.
IR Emitter can connect to LCD TV, LCD display, and projector or just about anything able to pull out refresh rate of 120 Hz. The technology works that every eye gets 60 Hz refresh and glasses blank the lens for 60 times in a second, so that 120 Hz display yields smooth 3D gameplay in 60 fps or so… I have tried the technology several times, and I have to say, it is really enjoyable. During the past couple of events, Nvidia demonstrated the technology using Call of Duty 5, Far Cry 2, Crysis Warhead, and Race Driver GRID and so on. Enjoyable part is that 3D Vision tech works on almost every game, and this immediately brings up the replay value of games that you already purchased.Theo writes NVIDIA's 3D Vision is pretty impressive and that you'll want to replay several old games just to experience them in 3D, but unfortunately it will be rather expensive. NVIDIA hasn't disclosed the pricing yet, but Theo heard it will be around $199. More info and photos over here.
