The spanish website DSLRmagazine announced via twitter (Click here /via noisyc) that Leica is working on two new models (one low end and one high end camera). In a second tweet they added that while the models will be shown at Photokina in September they will probably not be ready for the mass production. The may will go the Fuj marketing route that usually displays a model months before it’s ready.
Leica already said many times that they will make a mirrorless camera without the rangefinder optical system. And that it would be a high quality product (of course).
