I think it is no surprise that the 40D measures
up with the 5D so well and before we know it there
will be a camera that is noise free at ISO 1600 and
resolves even more detail.
The primary reason I like the full frame sensor of the 5D is the way lenses perform on it. Put a 50/1.4 on 5D and the image is noticably soft at apertures from f/1.4 to f/2.2 or so. While the 40D has nearly as many pixels as a 5D, they are 50% closer together. Packing the pixels closer together doesn't really gain you anything when your resolution is limited by the lens. So, while the 40D may have slighly lower noise, the 5D will still have a sharper image when shooting with fast lenses wide open simply because the lower pixel pitch of the sensor is less sensitive to lens softness. Personally, I think one of the primary reasons the 5D is considered a reference body for image quality is actually because its low pixel pitch makes most lenses look better. That said, unless you make big prints this distinction doesn't matter a great deal.

No doubt about it. You could go on and include DOF and corner
performance differences betwen APSC and FF format. Each camera
has its own purpose and place in the market. Thats why they are
there. Maybe the statement with no noise at ISO 1600 is bold,
but essentialy thats the direction technology is heading. Noise behaviour
is just one aspect of this. Dynamic range and contrast will improve
with new camera generations and each time we will look back and
compare an older "reference" model (5D) with a newer one (40D)
end be "surprised" by how close these two different animals are.

Wow, all that and it only costs 2 cents? WooHoo!
