In simple terms, it's when you take multiple pixels and connect them to become one "super pixel".
Basically, you lose MP to gain a better SNR.
That way, at least in theory, you can flip a switch and jump back and forth between a D3x-equivalent sensor and a D3s-equivalent sensor all in one body. Or something like that.

Lets suppose you need 4 pixels to bin into 1 (probably not true, as 4 pixels have 2 green, 1 blue, one red....). Then you end up with a 9mp image. If you want to have more successful binning with red and blue also... you would need 4 blue, and red, I guess?
That then needs 4 by 4 pixels? Which gives 4 red, 4 blue and 8 green ones. 36mp / 4 / 4 = 2.26 mp?
