The landscapes I shoot do not move very fast. I think that 4-5 fps, per the speculation, will be very adequate to meet my needs. The D800 is clearly not rumored to be a sports/PJ camera so there is no reasonable basis for disappointment in that regard. There is no factual basis upon which to say that the noise level will be bad. I am not expecting a super high ISO camera, nor is the D800 rumored to be such a camera. If the specs are as good as those stated on the Nikonrumors website I will be thrilled. There are many of us who are looking for exactly that kind of camera and will not be disappointed in any way if that is what the D800 turns out to be. The sports shooters and PJ folks should buy the D4.
