I agree with everything you said.

I took some pictures at my sisters wedding last weekend with the 5DIII and was very happy with its ability to focus accurately and quickly in very low light using any of the cross-type af points. And even though I believe the sensor is only 1/2 stop or so more sensitive, the newer software does do a much better job removing pattern noise. I had no hesitation shooting at iso 12800 and got results that (to me, at least) were very pleasing.
