I welcome LED televisions. 3-D? Not so much.
It's nothing more than the TV manufacturers grasping at straws to gouge even more money out of your pockets with a technology that is 57 years old but STILL hasn't made it past fad mode. Why? Because of Avatar. They think the success of one movie will drive this new technology and open your wallets.
Until they have 3-D television without glasses this tech is doomed.
