FYI, theaters use very high-end ($100,000+) DMD DLP and D-ILA projectors. Of course, they're very industrial in nature, and many have chip resolutions in the 2k-wide ballpark, so they carry the appropriate price-tag. Will CRT projecters eventually go away? Sure. Like turntables, eventually they'll be used only by a very few who still find their attributes desireable over whatever the technology du jour is (or they'll just revel in the nostalgia of it all).
In light of this thread, it seems relevant to tell you guys about something I saw last weekend. I saw the Windows Media 9 "high-def" version of "Step into Liquid" last weekend. Microsoft screened it for a small conference I attended - on a mid/high-end digital projector.
I'm not sure what the projector actually was, but I saw it from the floor and I'd guess a Barco or Christie S-XGA (probably in $40-50,000.) It was projected on about a 20'-wide screen. The screen was probably almost half the relative size (in my field of view) of our home screens. By that, I mean it was a 20' wide screen my viewing position was 40' away, compared to our HT screens, which might be 8' wide with a 10'-12' viewing distance.
Anyway, on one hand the picture was nice - colorful, extremely sharp, and pretty to look at - especially with the outdoor scenery contained in the surfing video. On the other hand, it was too contrasty with crushed blacks and hot whites. The color was a little week, not very rich. I frequently saw banding in subtle shading. For comparison, I've seen the Step into Liquid trailer probably a dozen times - on a CRT and on my desktop Sony FW-900 monitor - and the trailer is beautiful.
Folks, for a lot of us, digital projection just isn't there yet - even at 10 times what many of us could afford.
I bought a good used CRT for $700 almost two years ago. Unless something really crazy happens with digital projection, I'll probably buy another CRT after this one.
I won't make predictions, but maybe there will be something digital I want to look at (and can afford) in 3-5 years. Until then, I'll enjoy the beatiful picture a CRT makes.
