The GH2 has an oversized 18.3 megapixel sensor ... the 4:3 ratio yields the largest sensor area, while the 1:1 ratio the smallest.

Just to be clear, the reason for that is that the GH1/2 sensor doesn't cover the full image circle provided by the lens.   If you built a sensor large enough to contain the complete image circle then the 1:1 aspect ratio would cover the largest area compared to any other rectangular crop.

The big issue with that is that you'd be paying more for coverage that (for most people) would rarely be used.
