My D700 needs a partner (D800 wit or witout E)?

Hi all,

Im opening a photo studio in my town,so i guess some some wedding work and studio shots are waiting for me, now im not pretty sure if i did right,i ordered an D800 nextmto a D700 i already ownl and im really happy with its sharpness and allaround resultts,even pig prints look good,but i gues that there MUST be some sharpness improvements in 36mpx by itself,so anu sugestion if i missed something by not ordering the E keeping in mind im really happy with the D700, i got it since it came out,and NEVER let me down...!

Any thoughts?Expiriences?
