3D TV: I can believe this one, unless they go to the IMAX type of thing, with polarized goggles instead of those stupid click-shutter need-to-be-connected-via-USB glasses. Then they need to make movies and such that don't try to wow you with the whole "3D experience". Make the 3D more subtle and it will seem more realistic.
My 3D glasses are passive. I just put them on, similar to Imax.
However, the technology has developed to the point where it’s built into the tv itself, at least within the laboratories, which means commercial viability isn’t too far off.
