I agree with the point made above. You didn't have to go outside of POTN to find great high-ISO examples. There are plenty right here. To me, noise hasn't been a problem since the release of the 7D (original). If the shooter of a 7D, or any Canon body released since, is having problems with noise, it is usually for one or both of these reasons: not exposing properly, or evaluating noise at 100% view. Neither of those can be blamed on the camera.
