Looks like you already make you mind before even trying the d800, most of you expecualtions are based in a poor resolution video, shoot by someone else with a pre production, I preorder boths will do some test and them return one. for me clean 4:2:2 is a must really hope the nikon to be a good contender but never would make any desicition without trying it my self, dynamic range, holding in post and low light performance are important for me.
