I have not only seen the images, I got to shoot a Digilux 2 prototype for about ten minutes last month. Clearly, what I was shooting was using beta software, so it is probably not fair to make any real judgements based upon this brief experience. I will say that the images did look very good, better in my opinion than the other offerings from Canon/Nikon in the 5MP range. There didn't seem to be any serious shutter lag either, which was a real treat. This puppy does have a great Leica lens, something that should give all the competition cause for pause. The images were very sharp, and no signs of noise in the final JPG. It also shoots a proprietary RAW file in addition to the JPG's.
The two things I didn't like about it were the viewfinder and the time it took to write out to the SD card. I'm sure the write time will be fixed prior to product release, but that dang little TV set in the viewfinder is going to take some serious work as far as I am concerned. I won't go so far as to say "useless" as again, it was a preproduction model, but if this is the wave of the future we're all in for some major adjustments in shooting style. I simply couldn't get used to the constantly changing image as well as the rapid rise and fall in light amplitude. It would give me a headache in no time. The good news is the rear LCD was crisp, clear, and had good brightness at least indoors where I was shooting it in a bright room. Overall, I would say the Digilux 2 is a huge improvement from the Digilux 1 it replaces.
