Glasses free 3D doesn't look like the savior of 3D any time soon. Sharp's 8K glasses free 3D tv didn't leave great impressions at CES.

So let's be straight up: The glasses-free 3D on this massive TV just doesn't work very well. The TV was cycling through scenes from The Life of Pi and Frozen. The difficulty with any 3D is viewing angles: As you go from a dead center viewing perspective to a wider and wider angle it looks worse and worse. I would argue that Sharp's prototype barely has a viewing angle. The 3D effect barely works. It just kind of looks like the TV is broken.
The Samsung version is still 3 years away from market, and also plagued by 9 preset view points.

Vizio did better but is not going to market anytime soon either.

If it wanted to, Vizio could ramp up production within six to twelve months, but for now the company has no plans to turn the glasses-free 3D prototype into a commercial product. The main reason Vizio showed the prototype at CES was to gather feedback and decide whether to move forward.
It will be 4K with optional 3D glasses for now. Glasses free tech is too expensive with too many downsides.
