I swear, I think that we can see the future trend from the increasing ability of new-model digital SLRs to couple with old, "classic" lenses: as a lot of digital photographers are seeing, the old lenses tend to be better quality than all but the very most expensive new DSLR lenses.
It might take another twenty years, but the camera companies will finally release 'Digitial Film Packs' for all the principal formats of old-time liquid processing photography, including 35mm and medium format. The digital film packs will be tiny photo-computers with light-sensitive screens about the size of a single frame of exposed film. With the way that SS storage is evolving, each digital film would have about 1-10 gigs storage capacity. You'd pop it in your antique manual camera, crank 'n clack, and then do something funny to the film-return when your shot-count hits a 36 frame limit--then you'd crank and clack some more. When you were done, you'd push something to get the blind cover to close on your exposed light screen, take your 'roll' out, and pop it into a digital reader, that will by then probably have twice the pixel count of the best old processing film. I'll bet that it will be an expensive niche market for people who still consider manual photography an art (a lot of serious photographers with old cameras). The serious photographers I know are spending big bucks on negative scanners and multi-thousand dollar ink-jet printers for black and white photos. And some people (like me) are still buying old manual cameras. The day will come when all those shutterbugs who bought the classic Nikon SLR rigs and then sold the bodies for a song will be punching themselves.
