This thought has crossed my mind plenty of times. So my guesses are (assuming this is an ethical system deployed by Nikon)
- The batteries(body and grip) run in parallel circuit supporting 8 fps in D300. If using without a grip, the single battery may be unable to support 8 'number' of shots, i.e. it needs a refresh after storing 6.5 of them. The grip comes for rescue in that case. So it is less about the speed (6.5 v/s 8 fps) and more about the battery juice for 1 sec.
- (Bad guess) The memory controller which writes the data to the CF card may operate fast on a slightly higher voltage thus faster fps.
But the guess made by you does make sense as well, remember Nikon is market leader in gimmicks.
My point is how come the Pentax K5 and Canon 7D are able to achieve similar fps without a battery grip and similar battery profile as D300 if this is a matter of juice.
EDIT: The other day I went I checked the MB-D10 and while trying the same I backed out the idea of buying. I was unable to justify the reason of spending 15k (grip + battery). fps gain did not felt so significant, and I can achieve same backup if I purchase an extra battery for 2k INR. Note that the maximum physical length lens I have is the 70-300 VR, the lens is light and does not poise any handling issue since D300 is itself big and bulky.
