Hi Don. Your situation, shooting 90% portraits as a pro with multiple D3S bodies, I don't understand the move to the high pixel sensor (and large files) of the D800 models for your business, although I am not a pro portrait photographer and I certainly don't know your business details. My first thought would be a D4 if you are looking to change, including consideration of occasional personal landscape projects.
If you really want the D800(or E), I would go with the D800. I have owned both, currently the E model. Not enough difference IMO to put up with the increased occurrence of moiré. I do see increased fine feather detail when photographing song birds with the E model; however when everything aligns such that I achieve that extra detail, moiré is frequently there with it...sometimes 50% of photos from a given session with a bird depending on light, the bird, and how close I am (how much detail I am picking out of those feathers)
I am willing to stick with the E model for that extra detail in bird feathers (at least for now), but I would not take that risk if it was my businesss...in that case I would be photographing with the D4.
