I think I'll pass, but thanks anyway. His "great comparison" is based on reading the D600 specification and press release, so adds nothing to our knowledge. He doesn't have a D600 himself (yet).
I'll be waiting for one of the respected reviewers, such as Hogan or Mansurovs, to get their hands on the camera before coming to any conclusions. Incidentally, Mansurovs has a more comprehensive comparison chart of D600 vs. D700 here. They can be relied upon to avoid the attention-grabbing headlines, and they admit up-front that so far they haven't used a D600
