I received some information that Fuji will probably develop their own proprietary mount for their upcoming mirrorless interchangeable lens camera. Fuji is considering their new camera to be "first class" (source, page 10):
"Next spring, a first-class, mirror-less digital SLR camera will be launched"
Previously the camera was described as "premium" and will have “resolution and low noise that will surpass the 35mm full size sensor”. The most interesting aspect (at least to me) is whether Fuji will be using a full frame sensor in their new product. A prototype of the camera will be shown in January at the PMA/CES show.
