Okay, to confirm my suspicions, here are two samples using Raw Therapee without any special processing.

The first thing I'd point-out is the obvious moire in the scene which is kind of bummer. And the second thing is striking difference between the DPReview samples and these ones.
To which I'd add, I have no idea how they develop their RAW files, but... based on what I've seen, I really don't think they're doing the files justice at this point.
At any rate, I think the D600 really does strut its stuff in this particular example. Not that it matters since most people won't likely be shooting still studio images with their K-5's but...
I guess it does a good job of exposing some of the worst case scenario's that one might encounter with a AA' filter'less type sensor.
