DPReview has posted their in-depth review of the Nikon D600. Here is their review. I won't post a spoiler about their rating :).
I agree with almost everything they have said (except the grip - which they think is "comfortably deep," whereas in my view the D600's grip is not that great). For comparison, our review is here:

If you've read our review, there aren't any surprises in the DPReview review. However, I did learn something new from DPReview's review:
"You can switch between storage cards and image folders but you'll have to hold the 'BKT' button while pressing the up arrow key on the multi selector; a more convoluted and much less discoverable approach than the single button-press operation on the D800. "
Check out their review and if you haven't done so yet, check out our review too (for an amateur photographer's perspective).
