I am not sure Leica strategy for camera sales has ever revolved around price. I doubt Leica has ever been interested in the consumer market. Since the luxury goods market is really healthy--who has money except rich people--I think Leica has put itself in a great place. Leica is NOT competing against Nikon, Cannon, Olympus, or another company. There is no reason to compete with the technology of those other companies either.
As far as the rangefinder, that is what Leica makes. That is what put it on the map and keeps it there. They cannot but make M cameras. They can make other types of camera, but they are just a sideline.
What might be interesting to see if the cache of the rangefinder is a generational thing. Will millennials and the generation following them still think of photography in terms of the rangefinder? Who knows. Right now, the image of the rangefinder still has value. But it is built on historical value. Could the historical connection to the rangefinder as a tool to a specific genre of photography fade and Leica fade with it? Not sure, but it would be sad to see the optical rangefinder disappear altogether, even though I would probably never own a Leica.
