I'm not sure how 3D can catch on when so many people seem to have an adverse reaction to it. Lots of people I know who saw Avatar in 3D complained of headaches or feelings of motion sickness. I don't have true stereo vision so the whole effect is lost on me anyway. It just ends up looking blurry and distorted to me. I'm much more interested in 2K displays personally. That's something everyone can appreciate and enjoy.
