I think that in the future, the hybrid approach will be what saves film. Film makes a damn good sensor.
Film has been displaced as a sensor in areas where digital is vastly cheaper, such as a lot of motion picture applications because film stock is expensive. It's doubtful that medium and large-format image sensors will ever get cheap enough to displace film entirely. I say this as someone somewhat familiar with the semiconductor industry. However, people want the ability to edit and print digitally. They need it! All publishing is going to be done digitally nowadays. Very much color printing is done digitally nowadays.
If commercial forces have to use a digital sensor in order to get digital files, they will. It would be tragic to force them to make that choice, because as we know film has certain aesthetic and technical advantages as a sensor. I'm as much of an advocate for all-analog workflows as anyone else, but that doesn't change the fact that industry needs digital files. I really think there is a "scanning hole" in film right now such that there are more barriers than necessary in scanning. For example, I know my ektachrome slides have just as much detail as a point-and-shoot digicam, yet when I get a picture CD from a photofinisher, the quality of those digital files will often be inferior to those produced by the digicam. As long as this situation persists, people will forget film and use whatever gets them the results they need.
I think film can push on, but it will be the hybrid approach that saves it commercially. Think about vinyl records. There are still vinyl record pressing plants and you can still buy newly pressed vinyl records. Ironically, the vinyl industry was kept alive by electronic artists who valued the physical medium of the vinyl record for manipulation during playback, not to mention a heavy dose of traditional thinking. Most music cut into vinyl nowadays is edited and mixed digitally. Very often, it is actually generated electronically. But the analog playback medium was kept alive because it does certain things well, and because nobody hesitated to integrate it with digital editing techniques. If record mastering companies had made it difficult to get from digital files onto vinyl it would have died.
