I think Avatar pretty much put the nail in the coffin for glyph glasses outside of, say, print (I do have a pair hanging by but that's because they were used in Doctor Who/Torchwood, which is incidentally when I stuck them up there). It's such a lousy technology but for the longest time it's the only way you could do it across the board (the current glasses tech was used in IMAX screens but didn't go into regular theaters until Avatar). But the problem is there's still no way to look at one place and see two different things at the same time without those filters, the two eyes have to be seeing two completely separate things and without the glasses you can't control that.
Of course, if we're going to get better 3D display tech we need better 3D tech, the Cameron Pace system is great but it's HUGE, the size and ease of use seriously needs to come down... once it's not a hinderance to use, we'll get more REAL 3D content (not that post-converted bulls*it) and then we'll have the drive to REALLY adopt new tech.
But even after that, the amount of 3D content will be a drop in a bucket to the amount of 2D content we have-- a hundred years of movies, 50+ years of TV, IPTV being created at an astounding rate... while I do like good movies in good 3D a the theaters, I think we can pretty much forget about it at home.
