"For the D4 I would really have loved to have had even higher frames per second. 10fps is only one more than the 9 I now have, and that definitely isn't always fast enough, so likely 10 isn't fast enough either. I had hoped for 12 (like the latest Canon 1Dx)."

From my experience with shooting e.g., flying birds and running animals (but I'm sure the same holds true for e.g., football and other sports), even at 9fps, the position of the wings/legs isn't always pleasing in the resulting shots. This is especially true when shooting more than one animal in the same frame. An intermediate shot many times would have been the better one. Perhaps I'm being picky about this, but I like my shots to be as perfect as possible…
Anyway, hence my request for even more fps. And, yes, how fast is fast enough is a tough question. Perhaps even Canon's 12fps isn't enough. But as they have it (actually up to 14fps without metering and AF), I had kinda hoped for a more dramatic increase with the new Nikons.
