Nikon D3 produces files at 4256 x 2832: 12.1 MP
Sony A900 makes files at 6048 x 4032: 24.6 MP
If you take the diagonals of both cameras' files, the Sony is roughly 7269 pixels. The Nikon is 5112 pixels diagonally.
As you can see, the Sony only has about a 43% increase in linear resolution despite the doubling (100% increase) of MP over the D3.
In simple terms, the Sony may have twice the resolution, but the images you print can only be 43% larger while maintaining the same detail level.
