Update: this rumored new camera could be from Hasselblad.
Take a look at this prosophos.com blog post – it talks about a new camera with “unique shape”, M-mount, CCD sensor with a resolution greater than 24MP and “uncompromised image quality”.
I somehow have doubts that this will be a new Leica camera. There were some rumors last year about Voigtlander considering to start a new line of digital cameras.
If you have any additional information about this camera, you can contact me anonymously here.
