I have absolutely no worries whatsoever.
I saw Avatar in IMAX 3D and also in regular 2D.
My wife asked me which one I preferred.
It took me 1 second to answer her: I preferred the 2D Avatar.
Why?
It wasn't because the IMAX 3D was bad. Far from it. It was a COOL experience.
But if there's one thing I can't stand -- it's wearing GLASSES or any other accessories while I'm watching a movie (or listening to music). I can't stand it. It looks NERDY. It feels NERDY. It feels uncomfortable.
In my HT room, I'm lying on my comfy sofa watching my BDs. There is no way I'm lying on my sofa wearing some stupid eye-goggle to watch movies.
3D (& IMAX) to me is just another Been-There-Done-It experience. And now that I've been there, and done it, it is absolutely nothing special at all.
Oh, and my 73" HDTV already has 3D technology. And I won't even spend $1 on any 3D eye-glasses either.
