My guess is that in lower resolution mode, it uses all the pixels but stores one average value for two or four pixels instead of each value for each pixel.
A big question from me - which lenses have enough resolution to complement a 45 MP sensor? When I went to a D800, half my lenses weren't good enough.
I think you are right Dave. It is reverse interpollation which may help reduce noise as well.
Lens question is a good one. I have good glass at present no issues with my D3S, D600 and D800 but I think that stretching to 45MP may be too much for some of the older lenses.
