This is one of the oldest, most-well-beaten-dead-horses on APUG. Short answer, yes, film has a future. Long answer, it depends on the type of film. There may not be a future for color negative film. There is probably a very limited future already for color transparency (slide) film. Black-and-white film is much easier to manufacture in small volumes; it can survive even if the market continues to contract. So if you are interested in shooting film, just keep on doing it and don't worry.
