3D as it is is Bs IMO.
Early adopters are going to find that at some point over the next few years the "3D ready" sets will give way to something far more advanced - 3D w/o having to wear silly goggles anyone?
Or perhaps 3D will simply fade to something similar to laserdisk tech. All the while that special glasses are required to watch this 3D, it will never become main stream, never replace TV viewing as it is today.
I know consumer electronics/gadgets industry is a fickle one and things move on rapidly, it's a given in this day and age but sometimes it just can't be excused so easily - 3D is one of these. It is a gimmck, a prelude to something bigger, better and easier to live with.
I would save your money.
