Avatar only looked amazing because it was filmed in 3D- most other 3D movies are filmed in 2D, then converted- and look rather crappy IMO (and I find a lot of 3D movies to be a little disorienting and strain my eyes a bit). Plus, try watching a regular TV show, DVD or game on a 3D TV. I guarantee you'll wonder why you blew thousands of dollars on it.
So, for the time being,,, no. In 10 or 20 years? Maybe.
