Valid point about shutter vs mirror, but I don't think mirror flipping could be a battery issue. Both D7100 and D800 use the same battery.

The mirrors are not the same size though, the D800 mirror is over twice as large. Again, to get the D800 mirror to go from 5 fps to 6 fps requires going from 7 volts to 10.8 volts (those are the rated voltage of the EN-EL15 versus the EN-EL18 or 8 AA batteries).

large doesn't translate to weight. it could be same mirror in D4 and D800?

these mirrors could be lighter in D800, or could be same as D4. plus 8AA gives 10fps in D4.

So 6-7fps is already possible. adding 2 more may be a matter of firmware.

Adding two more to seven is adding is 28% more.

28.5714%

point of my post wasn't the limitation, but the possibility. since we both don't know the exact internal components - neither is wrong or right. for example canon was able to bump up the fps with the same camera (aka 7d) without changing batteries or hardware - just firmware.
