It's a reasonable and fair review I'd say.
It would appear that in some ways it's better than the d3s and in some ways worse. Clearly pushing an image 4 stops it's worse. I push my 5dii 2 stops though and that's just about acceptable. I would probably throw away something which needed 4 stops pushed. However, cleaner shadows would be useful at times - there's no denying it.
The AF system seems to be winning a real battle! Canon have pulled it out of the bag with that
People do seem to be complaining about the visibility of the AF points though. That's a concern / annoyance.
Generally though - I think we can all relax. Canon haven't completely messed up. It's not the camera everyone wanted - that much is very clear - but it's a worthy upgrade from the 5d2.
