This one is way different. The number (and budget!) of 3D movies released is much higher, and the necessary technology has been adopted on a massive scale by movie theaters (at least here). Going all digital made it possible.
Having worked in that industry for many years (and still with very close ties to it on a daily base) I can't see how it's getting dropped again like the colored glasses of old (or other experimental high-tech stuff we have seen in the fields of projection or sound). Even though there is a kinda fad to it (badly re-edited films with "3d" slapped to them), and technology will not stop where it is right now (that glasses will have to go!)
In "my" old multiplex here, 3d movies make up between 25-35% of all movies, but with a substantially higher share of audience (it's more the smaller, low-budget or 'arthouse' movies that don't offer 3d)
I guess we are witnessing a transformation not unlike going from B/W to color.
Yes, it's prolific. However, his point still stands. It still just looks like a bunch of cardboard cutouts. I don't find it immersive, if anything I find it a bit jarring. It reminds me of looking at the old Viewmaster slides.
I don't think 3D's niche is with movies, I think it's with gaming. Imagine a head mounted display that was just a pair of glasses, or maybe a bit bigger, that gave you a fully 3D field of view when you put it on applied to, oh, I don't know, something like a flight simulator, possibly set in WWII? Or an FPS/combined arms sim that had that kind of display and head tracking.
I think that's what 3D should be working toward, forget the TV/Movie paradigm. I don't think they gain nearly as much from 3D as gaming does.
