Lance, I didn't mean any negatives to your comments on the 800E. For my work which is much more weighted towards landscape, I find the 800 is plenty, plus I have followed posts on other forums where 800 and 800E images have been compared and it seems that the gap can be closed with sharpening. But that is a very personnal decision.
Your points made on frame rate and action are good ones. Here the D4 is a true leader. I have found the buffer issue not that bad on the D800 but I am in DX mode when shooting wildlife so the load on the buffer is much less.
