Now that's interesting! Fujifilm was tipped to release an update to the X-100 very shortly, but instead has just released a low(er) cost interchangeable lens mirror-less camera, and it looks like its pitched right at the NEX-7. The size is very similar, both have similar viewfinders (OLED 2.3 million pixels, Fuji's is probably from Sony) and both offer interchangeable lenses. It will be very interesting to read a comparison, but I suspect the Fuji will have the edge, despite its lower megapixels. This basic sensor is what many had dreamed would be in the NEX-7, and the Fujifilm has got very significant improvements, such as the lack of an AA filter. The high density Sony 24 MP sensor on the NEX-7 is known to be very trying on lenses, and on many Leica M lenses has fringing and colour banding issues.
The only thing I am no so sure of is compactness - the lenses do stick out quite away from the body and this certainly means the camera isn't pocketable, unlike an X-100.
I really think this camera will be a winner. The price is right, the lenses are excellent and the image quality will be outstanding.
