What is the optimal lens aperture, and what are the implications for the limitations of lenses on a 36-megapixel and higher resolution DSLRs?

I have read just that moment your test with the D4 as regards the optimal aperture and diffraction. Again a highly useful and true life test, thank you very much for that!
To be sure, the D4 is not for me (cost, bulk), but according to your tests I would not have hesitations using apertures from f/8 to f/ 11 in landscape photography to get reasonably sharp pictures (foreground and background, I know there will be some limitations but it seems possible). With my D700, I do also use f/16 if necessary, though I normally stick to f/ 8 - f/ 11.
But now there is "my problem": I have also read your optimal aperture and diffraction test for the new D800. Also a great, eye-opening test!
