IDK man that looks more like a 3d environment that allows your view of the environment to be augmented by a motion sensor (not really a unique idea but its a cool concept).
True 3D means things come out past the 4th wall (your tv screen) adding depth to them.
i believe what you have shown is just a 3D environment more like Detuned for the ps3.. which is not a remarkable or new technology.
exactly man that's why i said in my first comment that I'm still waiting for a similar technology with free glasses! , i know the ds one looks different i just gave the guy who was asking the link!
and i've watched the avatar in theater and it was great!, but i also played Left 4 Dead on my friend's nvidia 3d vision setup, to be honest with ya i wasn't that impressed! even thought his led tv was 240hz.
i believe sony's 3d would look the same as nvidia 3d vision yeah it's cool but not that great!, not to mention using the stupid glasses.
