I'd wish people would stop requesting that 3D technology not be tethered to the glasses. Face it folks, it doesn't work without them. What you are referring to is holographic images, and outside of CNN and Star Wars, we aren't much closer to getting that available to the public in general, so stop making ridiculous requests.
Oh, really now. The Nintendo 3DS shows at least one option. (and I might add similar glasses free tech was used in a laptop 2-3 years ago regardless.)
Then there's this article:

Furthermore there's the research company 'SeeReal'
Who produce tech that is then licensed out to mainstream manufacturers.

Let's see:
Among their stuff that's already available:
http://www.seereal.com/en/autostereoscopy/technology_cn.php - Autostereoscopic 3d display for PC's. No glasses required, but the effect only works if you're sitting in the correct spot. (sound familiar?)
http://www.seereal.com/en/autostereoscopy/NextGen.php - Similar Autostereoscopic system without the need for glasses. Can cope with multiple viewers and varied viewing angles, by adding in extra optics and eye-tracking systems. Not yet commercially produced it seems, but not a huge leap in manufacturing compared to existing LCD systems.
http://www.seereal.com/en/holography/holography_technology.php - Wait. What? Yes, you're seeing that correctly. This exists as a working prototype. Using similar eye-tracking systems to the previous one they've devised a system that can correctly account for how our eyes actually perceive light without having to resort to the near impossible task of creating a full hologram for every conceivable angle. (the eye-tracking essentially reduces it to about a 2 degree field of view, and 1 million times reduction in required screen resolution and graphics processing power) What's more, the prototype was built using off-the-shelf LCD components combined with high-end retail PC graphics systems to do the calculations.
The first prototype was shown about 3 years ago... Still, I'd give it another 10 years or so before this shows up commercially.
But... Tech that works in prototype form, and is relatively easy to manufacture to boot is hardly something that's restricted to the far future and wild sci-fi fantasies...
Honestly. 3d tech is far further developed than it's given credit for.
We're just playing catchup with whatever systems are currently the most economical to implement.
(And it just so happens the polarised glasses based systems don't require much more than being able to make a tv with a high frame-rate. - 240hz... Hell, on PC you can do it with any monitor that can refresh fast enough, and suitable glasses. - The graphics hardware from NVIDIA
and ATI have had the feature for more than a decade, it's just rarely implemented in the drivers...)
