A classic rangefinder digitally reloaded would surprise me, because that involves a lot of fine mechanics. Today, the production of such cameras would be quite costly. Leica's rangefinders are expensive, and Nikons remake of the S3 in the 2000s was also. Nikon had a lot of technical trouble with reviving this camera btw, if I remember correctly. Maybe today a part of the assembly of the mechanics could be automized with robots, in the days back it were done by low-paid women with petite fingers.
I am pretty sure that Canon will come up with a modern EVF ML body instead of plunging in such an economical adventure - much easier to assemble. If they stick with in-lens IS the body can be kept as mechanically simple as the first Sony A7 series. With the advancement of electronic shutters such a camera would be even more simple in the future.
