Just got mine yesterday. Have to say, I got the D4 for a variety of reasons but the first thing I did once the battery charged was to go outside and take bursts of photos at 10fps. That is an awesome feeling. Childish I know but it felt incredible. Now I am starting the task of setting everything up the way I want it. Was a bit disappointed with the first few photos (real photos, not the initial machine gun photos) but that is solely because of the fact that I don't have all the settings the way I want them.
