Two problems with your assumption:

1. If you think the AF performance is the same and the higher res is
going to accentuate the problem, why use the higher res if you can do
with 12MP? Down scale it.

True, if you want to down scale the 5DMKII images it will be no worse than the old 5D.

2. There are other electronics that are different in the 5D2 and they
migth have a say in the AF performance...

Speed is not the problem - accuracy is. No amount of processing is going to change the fact that the outer AF points does not have ability to "see" at larger apertures like the center AF point does.

Either way, when I tried the 5D2, I noticed the outer AF points were
a bit better than the original 5D... remember, this was side by side
using the same lens.

Canon says it is the same AND not even as good as the 50D (due to size constraints). But you say it is better. So you are making extraordinary claims here. That requires extraordinary proof. How did you test? What lenses did you use? Show us the pictures.

At least I've used a 5D2 and tested one... you're the one whose
claims are based on leprechaunian speculations.

Keep dreaming.
