How many lenses could you mount on a 5DMkIII?

that1guy, that's exactly the point I was trying to make -- thanks for doing it in a more succint fashion.  basically, it's a "nothing to see here, folks" kind of deal

No problem ;)

Just out of curiosity, does anyone know how many MP a full frame sensor would be if it were packed w/ the same density as the 7D? Just kind of curious and not wanting to do the math  ;D

An FF sensor is 2.6x larger than the 7D sensor, so 18MP * 2.6 = 46.8

downtime:
Yes, it would be 46.8 is correct at the same pixel density as the 7D (5.4mp/cm2)
But if you use the same pixel density as the 5D MKII which is 2.4mp/cm2 then it would be a 21 megapixel sensor.
I think my math is right. Maybe the mathmagicians can check that.  :)
I'm a bit picky when it comes to pixel density. Especially when buying point and shoots. But from the impressive quality I've seen from the 7D I'm optimistic that we could see a fantastic image from a 48 MP sensor in a 36 x 24 mm format.
Though I think it might need a quad core DiGIC 6 processor haha!

scalesusa:
Certainly every EF lens that Canon has ever made will out resolve it.

28MP is not a horribly high pixel density on FF, about 5.5 micrometer photosite size, slightly smaller than a 40D (5.7) but larger than a 50d (4.7).
