Optimum aperture on Canon 5D2?

I have run extensive tests on all my prime lenses on my Canon 5D and have found the optimum aperture for center and corner sharpness for each lens.

Will these change with the 5D2 because of the smaller pixel size?

I don't think the lens will differ but the aperture that you see diffraction (or how noticeable diffraction is due to the high resolution) will probably be on par with the 1Ds mkIII will it not?
