I doubt that prediction. Certain types of film may fall by the wayside, but a recent article I read stated that 120 may even outlast 35mm (don't ask what article, I can't remember).
However, witness the fact that the latest issue of Shutter Bug is devoted to film. And in that in that issue is a positive article about the new Tri-X from Kodak. Hardly a portend of doom.
Plus, with a Hasselblad 500CM, even if film disappeared you can go digital because the camera is modular in design. The most you would be out is the cost of your film backs.
