"Sensible" (cheap/good/convenient) 3D without glasses is simply not physically possible, as far as we know. The whole world has been searching for something like this since the first 3D movie was shot ~100 years ago.
Good 3D w/o glasses is possible today, but using multiviews (or holograms) to fill an area with lots of "stereo-pairs", which poses a problem from the transmission point of view or produces a problem with people sitting in the transition zones between views, etc.
In other words: we still don't have, and perhaps never will, have a good-and-cheap-and-convenient way to shoot-and-display-for-a-large-audience 3D without glasses.
Now, a different story is to do expensive (relatively compared to two-channels stereoscopic 3D), cumbersome, not-so-good 3D .... that, can be done without glasses anytime
In the future, stuff like CGI generated films could easily be sent to a large audience in 3D w/o glasses. Or a carefully designed theatre could be built were the seats match an optical screens and sends a few multiviews to cover the whole viewing space for all types of audiences (i.e. from children to people with large heads sitting off-center in their seats).
But, for the time being, we can all forget about (good, cheap, convinient, targetted to more than one-or-a-few-viewers, non CGI content) glasses-free 3D in the short (or perhaps even long) run.
But with manufacturers being able to put on the shelves 3D screens of over 60" and great resolution for quite cheap, I say stereo 3D (glasses included) does have a place at homes although, indeed, 99% of the people are going to use them to watch 2D content 99% of the time ...
The thing about 3D is that it hardly costs anymore to make a TV 3D ready than it already is (i.e., as mentioned, there are plenty of 120hz and beyond, all the way to 600hz, inexpensive HD TV sets in the market already today), so this whole 3D thing is but another excuse to try to get us to throw away our current gear and sell us another TV set or another blu-ray player.
But, since it's basically the same price, or a little more in case of blu-ray players, i.e., why not? It makes sense for manufacturers. And, of course, at first, they'll try to charge much more with the excuse ... "But it's in 3D!!!!"
Who wants to bet with me on how long it takes the industry to come out with a 55" 3D-capable TV full HD 240hz (superior to DCI 144hz) for less than $2000 (Hint: there are more than one already in the market, all the way down to $1700, just awaiting a firmware update and a HDMI 1.4 controller chip).

I agree, full color 3D in the home without glasses is just not happening any time soon. There simply is no technology in existence to make such a thing practical for a normal living room setting. Also, the cost of such a thing (if it worked at all) would probably be laughably outrageous.
Even if a TV could show 3D without glasses it would run the risk of merely giving a disappointing TV as an aquarium effect with everything receding inside and nothing moving forward.
I think anyone who demands 3D without glasses will be stuck avoiding anything in 3D altogether for the next 20 or 30 years. The glasses are simply going to be an unavoidable part of the equation until we have something like room filling 3D holographic movies that don't require the clutter and cost of a bunch of projectors lining the walls. Like I said, maybe 20 or 30 years from now there may be some sort of new revolutionary technology to make a lot of mind blowing things happen. I don't see it happening with any of today's technology.
Flat panel televisions are another problem. No new full color 3D system for HDTV is getting off the ground without it working in a flat panel TV form factor.
Given a choice, I think most consumers will choose flat panel televisions even if it means doing without 3D. They'll still pick a flat panel TV even if there are bulky rear-projection televisions or more complicated front projection systems that can do 3D with polarization or some other method. Flat panel TV sets take up less space and they look a hell of a lot better in a living room. That's a major selling point for a great deal of people, wives in particular.
I'm not surprised the method most likely to be used for full color home 3D is LCD-based shutter glasses synchronized to a TV set and Blu-ray player. What other method could work for a LCD-based or plasma-based flat panel TV set?
Panasonic, among others, is pushing for dual 1080p/24 streams on the Blu-ray disc using some sort of offshoot of the Bonus View technology. HDMI 1.4 is supposed to allow dual 1080p/24 streams to be possible.
As to the complaints about "field sequential" this or that, I don't understand the problem. New 3D TV sets, Blu-ray players, etc. will likely be running on a 240Hz clock, providing 120Hz quintuple-flash for each LCD lens. That's quite a bit faster than the human eye can see frames of motion. Human vision at best tops out a little over 70Hz. As long as the synchronization of the glasses works properly flicker should be minimal if even perceptible at all.
The biggest problem facing full color home 3D is the new equipment required to run it. Too many people have HDTV sets, Blu-ray players, etc. that are still fairly new, if not brand new. I am skeptical any HDTV sets currently available, even the true 240Hz ones, will be compatible. A whole new breed of Blu-ray players, PS3 consoles, etc. will also be required.
If 3D movies like Avatar, Toy Story 3 among others turn out to be huge hits it could help drive sales of 3D capable TV sets and Blu-ray players to those who haven't already upgraded to HDTV or have HDTV sets that are more than a few years old. My $3000 TV set isn't even 2 years old yet. I'm in no hurry to upgrade.
