Agreed. A direct comparison might be overkill here.
On my D60, most of the Raw only files are 6-9MB. Only a scant few dipped under 6MB, and only a scant few were over 9MB (mostly high ISO).
This is just speculation, but must mean that there is more randomness or color noise in my images. Maybe other cameras (maybe newer) do processing differently to reduce color noise, and that might reduce the overall size of the file.
