It is a real shame that Leica has chosen to retain the use of the CCD sensor with poor high ISO performance and the 230k pixels 2.5" LCD screen for the M-E, especially since they have recognized the need to upgrade those two important specifications in the new M. Since the M-E is essentially the M9, Leica should have simply lowered the price of the M9, bring in the M-E with the improved sensor and LCD screen for the current new M price and introduce the new M with all the bells and whistles (video, live view, etc) as their premium product at a higher price point. They might find that what many of us really want is just "the essence" of rangefinder photography found in the M-E but with the much needed upgrade to current technical specifications.
Any praise for making the new NEX cameras smaller is feeding into the illogical notion that smaller cameras are simply better. Take a look at the collection of lenses and one can see that the camera body is not very compatible with the zoom lenses that Sony has to offer, with the exception of the pancake type fixed focal length lenses. Instead, the preview/review should be examining if Sony has met the potential of the system by including additional features/controls on the camera. The specs on the NEX system seems to suggest the potential of a very portable system with high quality images, much like the Leica M did for 35mm photography in the past. Try not to compare the NEX camera with a point-and-shoot. Portable doesn't always mean having to fit in a pocket.
