Leica M9-M Monochrome rangefinder:

    All black camera body with no red dot or any other markings on the front, there will only be a Leica Monochrome engraving on the top plate (similar to the M9-P). The M9-M will  basically be a M9-P but with a monochrome sensor.
    The price of the new M9-M will be slightly higher than the M9-P ($8000) - my guess is $8,500 or $9,000.
