First, here is a mockup of the upcoming Fuji mirrorless interchangeable lens camera based on the leaked pictures from two days ago (source | flickr):
I also received some additional details: the model name of the new camera will probably be Fujifilm LX10. Still no 100% confirmation on the sensor size.
The new Fuji LX 18mm f/2 lens will have an excellent distortion control and will be slightly bigger than the Sony NEX 16mm f/2.8 lens:
The rumored Fuji LX 35mm f/1.4 lens will be smaller than the Sony NEX 24mm (the total length will be about 3-4 cm or 1.5 in):
