Although both the D3x and D3s are newer than the D3, it must have been the D3x-->D3s that had some bigger alterations. I seem to remember that there were some buttons switched around...and of course the cleaning system for the sensor was added for on the D3s.
So it sounds like the D3 and D3x are basically the same in operation, but the D3s has some controls changed slightly from both of them.
