No, I'm talking about actual glasses-free 3D television. No holograms, no fog.
For example:

Toshiba has an amazing looking TV that uses head tracking cameras to provide a 3D image as well. I don't know how it works, but it looked really good.
That's the direction most of the TV manufacturers are going. But regardless, since most televisions built nowadays have 3D built, in, it's not going anywhere. Yeah, people aren't rushing out to BUY new TVs with 3D -- but if it comes in the package for free, the market will eventually have enough content where lots of people will want to watch it.
