Leicaforum owner Andreas Juergensen got an official invitation for a Leica event in Berlin (see image on top). I am pretty sure they will announce the new Leica Mirrorless System which has been developed with Panasonic. The camera and the zooms will be built by Panasonic (and branded as Leica). The prime lenses will be made by Leica.
And it's also save to say that this will NOT be a Micro Four Thirds camera. This will be a completely new Leica system!
Thanks Leicaforum for breaking the news!
