Here's the thing: Nintendo has amde a device that can do glasses-free 3D. If not for that fact, I'd just wait for better glasses to come out. But now that we know glasses-free 3D can be done. So why go back? Yes, the method is not the greatest, but when all industires work on it, it will get better. We could eventually have glasses-free 3D TV. I'm just waiting for one of the three scenarios:
1: the 3D fad dies out
2: 3D becomes the norm, instead of a gimmick used to jack up the price.
3: The difference between 3D and 2D becomes so great that it would be in my best interest to get a 3D TV. (Hence why I never got an HDTV or Blu Ray. The older devices still do the job they do, it's just not as pretty to look at.)
