I too hope that film will continue to be available for many years to come. I only just made the switch to digital early this year with my "serious" camera (although I've had digital PS cameras for a while). So the experience of film is still very fresh in my mind. I must really miss it apparently, since I've bought two antique film cameras in the last few months. Both are 6x7 medium format, which in my opinion represents the pinicle of (relatively) portable film cameras, and they are so cheap now that even most professionals have moved over to digital.
My family also has very recent experience of my slide shows, something I think digital has yet to fully replace. With an old but decent projector I can display huge high resolution images in my living room, whereas with digital I am currently limited to a 27 inch monitor which cost several times the slide projector's price yet is tiny by comparison. Affordable digital projectors just don't have the required resolution from what I've seen. My teenage daughter is unusual therefore in having seen film in action, and indeed has used it herself extensively. Although she now has a T3i, she is still interested in film and is planning to take one of the few darkroom photography classes still available.
I waited this long to make the switch partly because it took me a while to accept that digital was really a viable replacement for film in terms of IQ and resolution, and partly because I didn't want a crop body; the 5DII price finally dropped to the point where I considered it affordable. I'm very happy with the 5DII and will continue to use it as my main camera, but I also plan to haul out one of the film cameras from time to time when I feel like doing something different. Especially with large medium format cameras, photography becomes a slower and more reflective art for me. Rather than pointing the camera at anything that catches my eye, I have to really think about the image I'm trying to capture. I know there is nothing stopping me from doing this with my DSLR too, but the film setups inherently impose more discipline. This makes them unsuited to sports and wildlife subjects, but I think of it as an advantage for landscapes.
Film is still readily available even in 120 roll format, although the range of choices is shrinking. At any sign of that changing I will likely order a large bulk shipment and freeze it for my future needs. But my hope is that it will remain available to those who appreciate its qualities. I expect the price will climb as the volume drops, and the most likely outcome to me is that high quality film will continue while any cheap stuff that remains (Wallmart film as sandymandy mentioned) will be discontinued. Low-end digital is so inexpensive now that there really is no need even for the cheapest disposable cams, and film will be produced in low quantities to satisy conoseurs and weirdos like me...
