Well, when you consider that the 1D mk3 has a 1.3 crop factor(28.7*19.1mm), while the G9 has a approx 4.8 crop factor(8.9*28mm)...
The pixel density in the 1D mk3 is far less than the pixel density in G9... thus people might draw the conclusion that it's possible to cram more pixels onto the 1.3 crop sensor, or conversely, the G9 has too many megapixels.
