This has probably been tossed around before, but I'm not sure how I'd search for it. I guess the question is, will M lenses be manufactured by someone, Leica, Zeiss, Cosina, for long enough that somebody will eventually make an affordable (under $1000) M mount body even if it takes 5 or 8 years? If they will, our M lenses should be "affordable" dual format (film and digital) someday,even if its longer from now than we'd like. My investment in M lenses will always be worthwhile if film exists at all, but the affordable digital would make it more so. I could even see a company making the body and just a couple lenses, knowing that the used market of lenses would make the body viable.
