I have both the 5D mkIII with the Canon 24-70 f/2.8L II and 70-200 f/2.8L IS II (and more) and the D800E with the Nikon 70-200 f/2.8VRII. To my eyes there is little to distinguish the resolution between the 5D III with the 70-200 and the D800E with the 70-200.

It really comes down to lenses. I remember a while back when DPreview did a comparison between the D2X (12 mp) against the IDsMKII (16mp).  The Canon  obviously produced bigger images, but the point being made over and over again was that Canon was pushing the limits of the lenses and that these limitations meant there was little between them in the end.

If we take a Nikon representative that DxO has measured for the D2X, the D300s at 12MP and compare with the D4 (16MP), and use the new high quality Nikkor 70-200 f/4VR then the D300s has 9M-Pix and the D4 has 13 M-Pix. So clearly has you seen DxO measurements of the D2X compared with the 1Ds mkII you would likely have seen a similar difference.

While the 70-200 VRII produces nice looking images with the D800, it doesn't resolve to the resolution that some of the new high end Zeiss lenses are delivering.  The Canon 70-200 is slightly better than the Nikon, but even then, it's yet to be seen if it too would stand up to such high resolutions.

It's hardly surprising that the IQ160 is out resolving both the 35mm DSLRs.  The 24mpx jump is nothing to sneeze at.  And then. there's the MF lenses, which are a good deal more expensive than the 35mm equivalents.

There have been some interesting comparisons between the D800E and the Leica S2 (also 36mpx), where the stand out was the Leica Lenses.

The D800E vs the Hasselblad H4D40 (40 mpx back), and the differences are negligible.

I don't agree that the differences are negligible. The Hassy shows considerable more detail and better tones. This is easily seen from the samples.

Camera Labs did a superficial comparison with a D800 and a IQ160, but again, they were using a Nikon 24-70 f2.8  (hardly a heavy weight when it comes to resolving power) on the D800 and a Schneider LS 80mm f2.8 prime on the Phase One.

But as compared to the IQ160 , I am not sure what you were expecting.

The diffence is quite remarkable and with a full frame 645 sensor the sensor area is around 2.6 times larger so it is to be expected that the resolution is much higher. Just like APS-C sensors resolve less detail than a full frame sensor with the same number of pixels. And there the IQ160 has 50% more pixels as well.

I'm also shooting with a Phase One IQ160 and the resolution of the 60MP of this camera is heads and shoulders above the two DSLRs! There are no measurements of the Phase One cameras with lenses on DxO, but my feel is that the IQ160 resolves at least 50MP or more with the best lenses.
