I found one substantive nit, a non-fair comparison -- Quoting the review: "Want to shoot lots of fast bursts of shots. I'm not sure that the difference between 8 fps and 10 fps is even close to justifying the expense of switching from a D300 to a D4"
I moved from a D300 with extra grip to a D4 for fast long bursts of images of bright events in very low ambient light stored as 14-bit NEFs. The D300 can only shoot and store NEFs at 2.5 fps, and not for long enough bursts. The D4 can shoot and store bigger NEFs at 10 or 11 fps for bursts longer than I need.
