It makes me wonder if Cosina ever made overtures to Leica or vice versa. Once the patent rights to the M mount expired everybody could get into the action, and Minolta already had followed up the joint venture CL with the Minolta CLE years ago. It isn't a matter of the world needing a reasonably priced Leica. We have reasonably priced Bessa and Zeiss bodies with M mount. Most users don't give a hoot as to whether or not their new camera will last for fifty years when the survival of film itself is an unknown.
Unless they've had experience using Leica cameras, or maybe the Swiss made Alpa cameras, they've never experienced such a well made and smoothly functioning camera. Perhaps they don't know what they're missing, but that just means that they're not missing it at all.
We now live in a throw away culture. Why get a 3 year old computer fixed when you can buy a brand new one with more features for less money than the repair would have cost? Cameras are no different in most peoples' eyes. The price of a full CLA on your M4 will buy you a brand new Bessa.
The news media has all gone digital and SLR. It had largely gone SLR before 1960 when the Nikon F displaced the S3 and SP and the Leica M2 and M3. There are no longer any heros out there shooting wars with film cameras, nothing to inspire the younger generation to embrace film. Kodachrome is gone. Film is now an art medium to younger shooters. Leicas, new or used, are an affectation for people with money. As working cameras, they have no use in today's world.
