Watch this space ---glasses free 3D is only 6 months away.
Thats why the big stores are desperately trying to shift 3D Tvs just now!!!
im sorry but 6 months is a very optimistic estimation, double it then add some is more likely.
im waiting for quad HD to be mass produced, its gonna look soooooo beautiful! (its 4 x 1080p for anyone who's wondering)
if you want my opinion dont go for 3d under 50" you dont get the full benefit/effect on the screeens under that size.
