Here Mr. Kazuhisa Nishikawa tested the latest DSLR body again! This time it's the K-7 with the latest DA lenses (and of course with one or two of the FA Limited that he likes to use). See:-

But anyway, I still like the K-m better for its skin tone reproduction and overall the image characteristics, see also what Mr. Nishikawa tested previously so that you can compare:-
