I won't be. I bought my last tv just over 6 months ago. It has a five year guarantee so I'll be sticking with that, and when I replace it, I will be doing so with a projector, not a tv, so therefore no 3d tv for me. However, whether or not the projector I buy, will be 3d capable, I don't know. It may be the standard, a few years down the line.
I have no real interest in 3d for now. I wasn't convinced by it when I saw Avatar because I found some things were out of focus a little, and the picture seemed darker with the glasses on. I am perfectly happy with regular content for now. I'll wait and see what happens, with interest, though, and the impact it has on gaming.
In any case, I don't see the point in it, unless it's on a really big screen. e.g. projector, or something like a 103" plasma.
I also found the glasses to be quite irritating.
