A year ago I was planning on buying a 3D TV this summer. What happened? I looked before I jumped and decided I would wait until the glasses were all inter compatible. I told Sony, Samsung, and Panasonic that until their TVs worked with Toshiba glasses, I would wait to buy. I'm sure some other people told them too.
Myself as a 3D enthusiast, and a prime early adopter, I feel that Sony failed to sell me on a technology that I was really looking forward too. And the truth is that you need early adopters for this kind of technology to ever take off.
I hope the TV companies get their act together and get a pan-company team of engineers together to create and implement a standard. If they don't do it next year, and Hollywood continues to produce terrible 2D->3D abominations, the 3D momentum is likely to fall below sustainable levels.
