Some initial impressions:
There's a tremendous -- in my opinion, unacceptable -- amount of color moiré in the ISO 2500 JPG sample, in the woman's hair and in the dog's coat. In addition, the WB is subpar.
The noise characteristics (see the 60mm Elmarit-R image at ISO 2000) look pretty good. The small amount of chroma noise is almost eliminated in LR with +18 chroma NR.
DR in the ISO 200 JPG is impressive.
In the 60mm Elmarit-R image, there appears to be dust on the sensor. An odd choice to make public.
Moire is almost not there on the DNG of the girl and black dog. See: http://www.l-camera-forum.com/leica-news/2013/02/leica-m-images-jonathan-slack/ The JPG conversion accentuated it. I rarely have trouble with moire on my M9P and D800E. Many subjects don’t provoke it.
after having a closer look now, I'm rather underwhelmed, puzzling why leica put such pics on the corporate site
he is a *very* competent photographer.That's why I always wait until a competent consumer/user posts shots with one of their new cameras. Most people are unskilled at post-processing, and everybody has an opinion as to what "good post-processing" means.
If I were Leica, I would hire a good photographer (not one who is friends of a buddy at Leica or a Leica dealer, or one whose name is "famous" or "highly-paid", for those just ride on that and are not out to impress anybody except perhaps a clique) that can produce a boring-yet-clinically-good set of photos using the whole range of the camera that could be taken apart and analyzed.
Some of these shots demonstrate capabilities under hand-held "true-life" conditions, but beyond that, this batch is lacking.
I am, however, slightly impressed (can't tell yet since these shots are one cat short of a cat test shot) by the high ISO DNG files.
I wish Leica relied less on buddies and/or hype-elevated testers and more on someone who would be eager to produce some inspiring shots.
One final point: if you have a discrete sampling system and it is not aliasing, your input is by definition limiting the resolution (i.e., you are oversampling, which is a good thing). In an audio system this means that the microphone or pre-amp do not pass frequencies higher than about 1/2 the digital sampling rate (often 44 kHz), or there's a low-pass filter in the sampling system; in an optical system it means that a lens has aberrations, there is motion blur, focus is imperfect, etc.
This is why, in scientific imaging, we either take care to over-sample the diffraction-limited resolution of our optical systems, or we employ some sort of low-pass filter.
If you aren't seeing moiré with a D800E or a digital M, you are oversampling. In other words, resolution is not limited by the sensor, but by your lenses, your RF calibration, or your shooting technique (critical focus; motion blur). If you're shooting handheld in available light and seldom achieving truly critical focus, you won't often need to worry about moiré with modern high-resolution cameras.
Canon's engineers understand all of this, they make good lenses, and they sell their gear to critical users, and apparently their sensor design is dominated by their engineering staff. Hence, all Canon DSLRs have AA filters. Nikon's and Leica's engineers understand it as well, but their marketing people know that people who don't understand discrete sampling don't know enough to care whether they are getting accuurate rendering or imaginary detail generated by the sampling procedure. Nikon has enough professional pride (and volume) to sell the D800 in both a professional version (D800) and an amateur-bling version (D800E). Canon does not make this concession.
Finally: you will note that the world's leading manufacturer of both CCD and CMOS sensors is Sony. Like Canon, Sony does not sell DSLRs without antialiasing filters. It is telling that the only two major camera manufacturers that design and fab their own sensors always use antialiasing filters. By the way, the XTRANS sensor from Fuji aliases as well (this is readily detected with good technique and carefully chosen subjects), but its design does seem to do a good job of suppressing color moiré, the most visually objectionable form of aliasing. It's an interesting compromise, if not a complete solution.

i think that Leica chose these images for precisely what i bolded above... i'm sure he has many more images that would suit your aesthetic -- let's just hope Leica allows them to be released soon.
(i think they got burned a bit on the Jacob Aue Sobol pics and so decided to go the opposite direction here... Jonathan Slack -- the very same photog who took these shots -- had a better set, imo, with his pics from China.)
