Yes, definitely: D3s. Almost certainly: D3x. And probably, by a whisker: D3. And I'm sure that the new Canon 1D X will be too.
Nobody's claiming that the D700 is a poor camera, or even merely a good one. But the DX bodies are pretty darn good too, and really, for most things, they are either equal or not far behind, especially the latest ones.
