Have I read same test? Excuse me for quoting literally Phil Askey -I hope with his kind permission-

"A check of the detail crop however shows that at ISO 1600 and 3200
we're losing detail to the smoothing effect of noise reduction. A quick
scan of the graph below shows that noise levels between these cameras
are actually quite similar up to ISO 800 (with or without noise
reduction), with noise reduction switched Off the D2X's ISO 1600 noise
is marginally higher than that of the EOS 1Ds Mark II. Set noise
reduction to High and you get the cleanest looking images and lowest
measurable noise levels but at the expense of image detail (see samples
below graphs)"

"In development terms this new sensor may not be as mature as those
found in Canon's digital SLR's but it real terms it performs almost as
well, the only difference seems to be Nikon's choice of standard
sensitivity range which is ISO 100 to 800. Turn off the High ISO noise
reduction and shoot at ISO 1600 equiv. (HI-1) and noise levels will be
higher than we'd like, turn noise reduction back on and you begin to
lose detail (my preference is keep the detail as the noise isn't that
objectionable)."

"Having now matched the in-camera sharpening we can see that while the
Canon's resolution advantage can be seen in areas of fine detail it's
not a storming lead"

Leica DMR option for 1.3 crop sensor is an economical decision consequence of cost influences and it's the first time I see Leica  not going to the top notch absolute quality but is doing concessions to practical factors. May be it will be necessary for survival.
