D700 - What did i miss?

Kerry, you stated high speed ​and ​high performance, which implies they are not strictly the same.  One way to interpret that would be looking at the AF system, and some might construe that to mean the D800 somehow doesn't measure up to the D700 in that regard.  Something else that can be read into high performance would be the mirror black-out time.  Another aspect of high performance would be how a camera performs in low light.  Durability would be another thing that (I think) would qualify a camera as being high performance or not.

Yes, I do appreciate extra fps, better AF, and reduced mirror blackout time.  In light of all of that, I would have just said the D700 enjoys 3 fps full frame advantage when using the MB-D10 (with appropriate batteries) while the D800 at 1.2x crop can match the D700's 5 fps without the MB-D10. I would add that a lot of photographers never used the MB-D10 on their D700 bodies, so for them the difference in fps between the two cameras came down to the 1.2x crop.

The question was about the D700, not the D4, and you said as much in your initial reply.  We could have asked the same question then about the D3 and D700 since the D3 could go to 11 fps, and in that context the D700 would not the the high speed camera, just as the D2x would now be relegated to not being a high speed camera.  I would argue that any camera that can do 5 fps or faster and has an AF system that keeps up with that can reasonably be called a high speed camera, but I'm sure there will be those that disagree just as you do (and I'm fine with that).

That wasn't my point.  I'm simply asking for some clarity here.
