People have been guessing for over 10 years now. Predictions on many of the main photog sites (photo.net) would say "film will be impossible to get in three to five years..." but that was almost 10 years ago now or more. If color or slide is your forte then perhaps one day little will be found but for b&w I think it will never cease to be available. Maybe not at your local druggist but easily found by mail order.
