lol TV manufacturers are investing way too much money in the development of 3D TVs for it not to be the next thing. Japan is currently getting all the 3d tv love with the release of 3d TVs that do not require viewers to wear glasses.. once that technology is cheaper so that they can be used in TVs that are much larger than 20" we will see them in america. But don't fool yourself into thinking it's a fad at this point.
Look how far HD tv has come over the last 5-10 years now just about every broadcast is in HD do you honestly think that 3D won't be at the same point in 10 years? I'm sure the PS4 will almost completely evolve around 3D it's going to be the major seperation between PC gaming and Console gaming going forward.
