A bit of net scouring and I found a link to The World of Canon Sensors that has some explanation

I also found this link that explains the expected differences in MP count and sensor pixel pitch.

Nothing to change my prediction for Nikon in post one. The question is when. Just wish I had an Hs to simulate it by stitching two portrait orientation shots together to compare with a landscape format X image.
From Adey's post re a possible Sony full frame sensor, and picking up on Leif and Joes comment on the megapixel race, then the question is, will pub bragging rights continue, as the full frame sensor gives them more opportunity to go to 20mp. ( Marketing mans delight
) Higher count than the 1DS MkII but not necessarily better image quality.
