I think you are exactly right Russ.

I agree. For those who's primary photography is portraits, weddings, and landscapes, the D800 is the ideal upgrade. For those worrying about noise with this upgrade, they should stop worrying. It's high ISO/low noise performance will be just what the doctor ordered.
For me, as a travel photographer, who also does some news coverage, plus being out at least weekly for wildlife photography, I'm going with the D4 to replace my D700 which is nearing the end of its life. With the D4 I'm getting an improvement in resolution, and keeping the high speed capability I use constantly, and am maintaining great essential high ISO/low noise. Plus now I'll have video capability in my DSLR which I didn't have, for travel and news clips.
