There is software and hardware implementation I think. Having 3D TV is essentially using hardware while a few PC games can already do 3D using normal monitors with software. Of course hardware implementation is better but think TECHNICALLY the answer is no. But the TV makers are not gonna tell you that.

Both implementation need glasses. There is passive ie the red and blue glass and active ie shutter glass. Active ones are those that need electricity and review is that they are better cause passive basically is showing you half the brightness at half the frame rate.

And Nintendo 3DS is already 3D without glasses. so no need to wait till 2012 end of the world Main problem for this is viewing angle.

I don't intend to get a 3D TV soon. Jaws was in 3D also like 20 years back and what happened after that? Until they can get glassless implementation with good viewing angle I think it will be at best a niche if not a fad. BTW 3D is bad for eyes and people with health problems like dizziness, and especially bad for young children... for now
