I'm seem to not care about 3d at home. Which is wierd because I was excited about HD back in the day, and all over adopting that format. I couldn't seem to care less about watching 3d at home on a 40-50 inch tv.
Sometimes if the movie was actually filmed in 3d (and it looks good in 3d) its worth seeing in 3d in the theatre. From my experience for most movies its an afterthough, and the 3d really isn't worth it.
My guess is though. The tech will become cheaper, so eventually it will be built in all tvs. Since it also uses bluray, at some point most players will also support it. Will the masses pay extra for 3d content though?
