Sometimes in these "new film camera" threads, I feel compelled to say that the most practical route to a new film SLR would be for some company like Nikon to take much of a digital SLR body and build a film transport mechanism onto it. They already have the body, shutter, AF system, exposure, control interfaces, etc. It would be like reversing the way that the D100 body is a descendant/cousin of the N80/F80 body.
This is, from an engineering viewpoint, possible, but business viewpoint, an almost certain money-loser. But that's also not what many people want in a new film camera. They want a new mechanical F2 or similar, not something that looks like a DSLR. I get that, but the inflation-adjusted price of a new 1970s F2 would be around US $3000 in today's dollars, and that doesn't seem like a viable product either.
This thread is about what would you want in a dream project, which is perfectly fine. But it isn't reasonable to then wave hands and say that modern manufacturing should be able to manifest the dream into reality. Modern manufacturing makes things cheaper in part by replacing mechanical systems with electronic systems.
