wedding photogs excited by D4 or D800?

I see a lot of posts saying the rumored D800 will be targeted towards wedding photographers and studio shooting, while the D4 will likely appeal to sports/photojournalists. Is it just me or do the specs for a D4 (assuming the ISO performance is better than the D800) looks better for shooting weddings?? I'd much rather have the tank build of a D4 and better high-iso performance then a high mp sluggish d800....
