Bottom line, I know the D800 is superior in every way especially when using top notch glass, i.e. Zeiss, again to go all the way with the D800 or any other high mp camera, everything has to be perfect or your wasting your money.
That's largely true, but I don't think the D800 is in a special category in this regard. All the recent cropped-formats from Canon and Nikon, the 50D, 7D, D7000 etc. have at least equal or greater pixel density than the D800 and would therefore require the same, or even higher shooting standards than the D800, for optimal results.
Loss of lens performance at the edges and corners has always been a disadvantage of the FF format compared with the cropped format used with FF lenses. However, the fact remains that a D7000 when used, say, with a 100mm lens, requires an equally stringent technique as a D800 used with the same lens, the difference being that the D800 provides a wider FoV.
For owners of the Canon 7D, which has the pixel density of a 46mp full-frame, techniques have to be even more demanding to achieve optimal results with a FF lens, whether it be a state-of-the-art Zeiss lens or not.
The lens-review site, Photozone, has a number of examples of the same model of lens tested with different cameras of the same brand but with different pixel counts, such as cropped-format and full-frame. Even with an average zoom lens, the camera with the higher pixel count always delivers more LW/PH.
I just placed my order today for a D800E. I've been a bit undecided about the choice of the D800 or D800E, but I've always felt that any need for less sharpening has a benefit regarding noise levels. This advantage has nothing to do with moire considerations. One would expect D800E high-ISO shots to be either noticeably sharper or noticeably cleaner compared with the D800 shots.
Another advantage of the D800E is that I'm probably going to receive the camera sooner. For that I should thank Bart and Guillermo and Bernard and BJL, and all those who have been so vocal about the horrors of moire and aliasing artifacts, for helping to shift the major demand towards the D800, resulting in a shorter waiting list for the D800E.
