The new lens is better only at the extreme edges while the old lens is better in the center to midzone by these charts.  Keep in mind this is comparing f/2.8 with f/4.0 so stopped down to f/4.0 the old lens will smoke the new one by significant margin (at the wide end).

The F/2.8 is marginally better in the center and midzone, while the F/4 starts to get better in the last third of the frame, and is massively better in the corners. Now, as to how they will compare when both are shot at F/4, no-one knows at this time, as we've got nothing to go by. Apparently you believe that the F/2.8 will smoke the F/4.

The 2.8VRII becomes significantly better stopped down to f/4.  It was harder to see on the D3 but it's very obvious on the D800E.   It's also reflected in the online review site numbers.

I'm hoping the new lens is superb @f/4 when making real images on the D800/E but not sure given the calculated MTF we're discussing here.  Requiring f/5.6 or f/8 for critically sharp images makes the lens less useful to me.   It does look stronger at 200mm than 70mm.
