The latest rumor: in the next 30 days Leica will release a new point and shoot camera that will be based on the Panasonic ZS7 model (Leica will create its own housing for the new camera). The rumored model name will be Leica C-Lux 20. This is not really a surprise, since the Leica C-Lux 3 model has been discontinued for a while.
Not sure why Leica decided to go with C-Lux 20 model name instead of the expected C-Lux 4 model.
No word on the Leica 35mm Summilux-M replacement yet.
