Well, at some point when the used market dries up enough for any product that demand generates return of "new" pricing, then it makes sense for some company to consider producing new ones.

If we keep the demand for film strong enough, and for long enough, we just might see the return of specific film camera styles. Even if they are made of titanium ans carbon fiber or whatever materials are in vogue at the time of their production, they will probably be quite good.
