While we are dreaming...How about a Micro4:3 format sensor in a CL type body with the same match needle metered manual exposure only...(ok...maybe Aperture Priority too if you must) an M mount (to use your classic M or LTM Leica/CV 24s, 35s and 50s) and a new 12mm f/2 M mount lens? Dial-able frames in 24, 48, 70 and 100 (35mm equiv.)
Given a price point of $1k or less, this would tempt the same market that the DP1, the Canon G10 and the Leicasonic DMC-LX3/Digilux 4 attracts now.
