What many people do not realize is that with the paradigm shift with digital comes the upgrade/obscolecence cycle that cinema has never had to deal with before. For 100+ years upgrades in picture quality came in the form of new film print stocks and were free. If Kodak made an improvement in grain size, color or contrast, everyone eventually got the improvement in picture quality for free. Of course there were advances in lenses and light sources but those were not mandadory or compulsary upgrades. With digital, all these image quality variables are now tied directly to hardware (not software). True there was 70mm but that was not available for every release and most theatres could afford that equipment for a premiere house or two, if they wanted to. Technology shifts of the magnitude of digital cinema are difficult and expensive, I doubt the commercial cinema industry could exist as we know it with the upgrade cycle that other industries sustain...without $25 ticket prices and $15 popcorn. And, as mentioned in another active thread here, most people don't care about picture quality...if the story is good, audio is decent and picture is resolvable, most patrons are happy. In the late 90s people would seek out digital audio theatres and even the new stadium seating theatres, no one is asking for the 'digital cinema' theatres or the '5,000:1 contrast' theatres.
