I think film will continue to be used by the motion picture industry for at least another 15-20 years, and will remain popular with art photographers (i.e., the people who frequent these forums), but as a mass consumer format, the writing's on the wall. For point-and-shoot and strictly utilitarian photography, digital is too inexpensive and offers too many advantages for traditional photography to stand a chance. I'm just happy I can still get my pictures developed at the local drugstore at reasonable cost and can still find Kodak and Fuji film at the supermarket for $2-3 a roll.
Who knows what the future will hold for film if the economy takes another downturn (which I think it will).
