It's tough to see through my crystal ball reading D-Cinema predictions for the future, but that being said, here are some realities:
1. Majority of 35mm film stock used to be sold for comsumer cameras, NOT motion picture prints. We all know what has happened to consumer photography. What will that mean to raw film stock prices as we move forward, and how will the studios respond to increasing print costs?
2. Regal, AMC and Cinemark will begin rolling out 14,000 screens of D-Cinema conversion next year. This is a 4-5 year process, by their own admission. There are several other planned deployments from AccessIT, Digiserve, Technicolor, etc. Seems like film used film equipment will be readily and cheaply available.
3. Cost of D-Cinema equipment has dropped in half in only two years. What will happen in another two years, especially will the volume of sales noted above?
4. Virtually all US studio releases are now available in Digital.
Based on the above, film will be around for AT LEAST another 5 years. I would predict another 10 years, but that's just my opinion. It is safe to say, however, that our industry will be 99% digital at some point in the forseable future. Everybody should be planning for it, if only by upgrading sound systems to meet the DCI spec.
