I seriously doubt that all instant film products will disappear from the market. Even if Polaroid itself were to cease to exist, somone would buy the rights to produce the films, as some of them obviously are still moneymakers. The number of available types of film may shrink and/or the prices may rise. But knowing how many pro shooters still go through boxes and boxes of polaroid each day they shoot, I wouldn't start to freak out about lack of future supply just yet.
