This is true, but I imagine it may still be a novelty more than something that catches on seriously, especially as people are lukewarm on 3D films as it is and this sort of thing is always a problem for something like 10% of the people who try it. These always seem to pop up every so often, didn't Sony put out a 3D HD set recently?Except this is a light, low latency, high fov, stereoscopic 3d VR with 2013 technology...and all at a reasonable price. It hasn't been done.
... Plus technically it's not something new and never before seen, it just may be something finally reaching the point where it's actually practical much like the Wii Remote versus the Powerglove, except I don't think this will get that marketing push to be widely adopted.
