Heh, I don't think digital is going to die. Face it; film is a fringe cult for those who value the particular qualities it offers. Your average snapshotter and a good number of serious amateurs and professionals are now completely digital and that's not going to change.
I think we're seeing a revival in interest in old film cameras as a consequence of the digital revolution though; look at the hot market for medium and large format cameras on ebay. Lenses and cameras that used to be considered junk are going for a small fortune these days. At the same time, with most professionals going digital, amateurs can now afford nice hasselblad and RB67 systems, which will doubtless fuel interest in film.
Eventually things will stabilize, and digital will dominate the photographic marketplace, and film will be going strong amongst artists and fringe lunatics.
