D800 handheld hype nonesense - model shot handheld with 200/f2 at 1/30

It's only silly when taken out of context.  Fact is, you often (but not always) need to use a tripod to get maximum resolution from lower pixel density cameras such as the D700; therefore yes, with a D800 the threshold for either optimum or maximum resolution increases by 70% of a stop compared to the D700 if you are printing each at their largest acceptable size ("acceptable" also being a point of contention).  Frankly, I'm not buying what is implicit in the OP's argument here, that he is getting more from the D800 than he could from the D700 at 1/30s, and the arguments you offered was about shutter speeds in the neighborhood of 10x as fast which suggests you aren't going to argue that either.
