im still waiting for 3d TV's with no glasses needed...now that would be awesome.
I'm waiting for a 360 degree spherical OLED 3D room-television. In effect, it will be much like a VR headset, only costing as much a small house. : 3
The problem with glasses-free 3D is that you need to direct a pair of different images to the eyes of each viewer. So, either the viewers need to carefully align themselves with some predetermined positions and not move their head more than a few centimeters to the left or right to retain the 3D effect, or the screen needs to perform some form of eye tracking and adjust lenses on the front of its panel to allow viewers to sit wherever they want and move around. The first option would be more or less impractical as a consumer product, since being forced to sit in precise positions to properly view the 3D image would be far less comfortable than putting on a pair of special glasses. The second option tends to only really work well for a single viewer, and would not really work when multiple viewers are involved. So, you don't hear much about glasses-free 3D TVs for the simple fact that at least with today's technology, it probably wouldn't work very well under normal usage scenarios. The Nintendo 3DS was able to get away with this since it's a handheld device that the user can better position to give them a proper view of the 3D scene, though even there it can feel a bit restricting. They added eye tracking with the "New 3DS" to allow the viewer more freedom in positioning, but still the device is only intended for a single viewer.
And the most important thing you're not considering is that VR offers a completely different and far more immersive experience than simply viewing content on a 3D screen. In VR, one is actually surrounded by the scene, and isn't just watching it through a little stationary window. It's not simply a matter of having a stereoscopic effect, as that's only a small part of what VR involves. The main part of VR is that you can look around wherever you want, and feel like you're within the environment, which is something a television can't really replicate.
