Then they should have made the top frame rate 4 fps!! I never said it wasn't purposeful, just thoughtless. They were underbuffered already and said, "Screw it - we're not changing any of it", when it was an acknowledged deficiency (I spoke with several Nikon reps about it in NY last fall and they all acknowledged the buffer on the D7000 was undersized).
I shoot birds in flight. Get an eagle flying by and you want 3-4 seconds to have a shot at the image. Shoot motorsports, one second isn't enough. You want to get the kid kicking the ball, sure. You want to get the soccer player running down the field with the ball, not quite. Sure you could compromise, but why, because you bought a camera advertised at 6fps specifically for that purpose!! It may be ridiculous to assume you have to shoot at 6 fps all the time to get a good shot, but in certain genres of photography it's certainly not ridiculous to want to when you have a camera that's supposed to be able to do it!! You may be more than happy to settle for that, or for shooting a video. Not all of us are just looking to take snapshots of our kids, and that's a point you just can't seem to latch onto.
The fact is, Nikon doesn't have a DX camera introduced in the last 2-3 years that will do either well. Not one!! There is no choice other than to compromise. And that's a problem. Everything else is a one-sided compromise by the consumer. I will continue to cry BS, particularly because I've had extended conversation with folks from Nikon about this problem since the D7000 was still a puppy.
