I have to agree here. Interesting how also there is a HUGE number of D700's for sale here and on Craig's list and other used equipment sites. I have never seen so many. All upgrading I guess. The D3s is a marvelous tool for indoor sports and any low light condition. The D4 appears on the surface to offer improvement to that. We shall see I guess. I plan to RENT one prior to sinking the dough however. I want to see if it really can take my indoor sports shoots up to 1/800th + at a reasonable ISO without degradation of the image. Time will tell I guess.
