Another way to 3DTV without glasses?

Another Glasses free 3D Method

Everyone wants to see 3D drop the need for wearing the 3D glasses.
The technology is there in the TV's but would be too expensive to launch currently so is said to be several years away.

This article says we have glasses 3D coming very soon which sounds very good.  Sounded good indeed BUT I was quite surprised when I listed to it and heard what you need instead of the 3D glasses.
