We from 43rumors do believe that Leica were really close to join the M4/3 system. But at a certain point they choose to not join the MFT world. Now Luminous Landscapes suggest them to abandone the rangefinder tecnology in favour of the new “mirrorless” camera systems.
That’s what Luminous Landscapes says:
“I am arguing that the current M9, and any other camera built further on the viewfinder / rangefinder paradigm, has become an evolutionary dead-end. It serves to support the superb range of current and previous Leica M lenses, but it does so with a design brief that is now at least several decades out of date.
So, now the controversial part. Viewing. Since this camera will use M series lenses it can not be a DSLR. Some pundits are arguing that this design’s days are numbered in any event. That means either a live view LCD screen and / or an electronic viewfinder, and Live View pretty much means a change to CMOS from CCD.”
