There is a huge (over)supply of used film cameras on the market. Just look at the published CIPA numbers: From 2000 - 2007 alone more than 85 million (!!) film cameras have been sold. There are so much film cameras on the market that it will last for decades to come. And there are already new repair companies exploring the business model we have established already for decades in the classic car and air plane scene: Keeping items running for an unlimited time.
Nevertheless we will see a similar pattern as we've already seen with mechanical watches and turntables: Lots of new models, partly from new and innovative manufacturers (we have first signs of it with Chamonix, Intrepid, Reflex, Ponf).
Digital camera sales are on a all-time low and further decreasing. In the mid term, camera manufacturers will look for further attractive niches. Film cameras will be one of them.
