Some of these speculations seem doubtful. For example, the top dial on the current model also is unmarked, except for a single letter "A" (for auto shutter speed selection) so the idea that the dial might be reprogrammable lacks support. Also, the teaser illustration does show a front viewfinder window but not a rangefinder window, so there's no assurance that this is even a rangefinder-focusing camera. Could a hybrid EVF be in the works? It would be funny if they beat Leica to the punch on this concept...
