The current Leica M-E model
Leica is rumored to refresh the current M-E model ($5,450.00) in the next few months (most likely at Photokina in September). The new camera will be called M-S or M-E2 and will have the same 18MP CCD sensor with updated LCD screen and new battery (probably from the M 240).
If this rumor is correct, this would be a clever move from Leica since many people prefer the specific look of the photos taken with the 18MP CCD sensor.
