Thanks Bryan. I agree that in good light condition and with balanced light any digital back with more pixels than the D800E can overwhelm the D800E.
I have stated that I only shoot milky way, sunrise (backlight) and sunset (backlight). When I shoot directly against the sun, the image quality is bound by shadow noise (dynamic range) because I have alignment issues with bracketing. For my specific use cases when I print large, the D800E (Sony CMOS sensor) outperforms any CCD regardless of number of pixels, sensor size or superiority of glasses.
