Seems like a clown to me, the RiceHigh of Canon perhaps? Why is he comparing a 10 megapixel camera to a 18 megapixel camera at 100%? Downsample the 7D picture to 10 megapixel and the comparison might be somewhat meaningful.
Might also want to wait with comparisons until the 7D support in ACR comes out of beta stage...

My suggestion is that you read a bit futher down the page. There are folks there with dozens of Canon bodies chucking the lot of them for lack of getting them repaired/fixed/replaced to their satisfaction. Of course, there are naysayers all over, but are
all those posters wrong? I do not think the thrust of some of the later comments was over megapixels -- rather over AF and other issues.
AFAIC: I always prefer same-sized image parts even among different MP cameras. DPR tests differently.

Of course, on a per pixel basis, the 7D has more noise. That said, make a 16x24 print at 1600iso and the 40D will not only have more noise, but have less resolution. As I own both, and have compared, this isn’t just a blind opinion, but based upon actual prints.
Autofocus has been dead on and accurate for both stationary and fast moving targets. I photographed my daughters basket ball team play and had no misfires. For weddings, it has been superb in low light.
The real issue I believe, is less of one with camera focus and noise….but more of one with people not understanding exactly how big a file they’re looking at in a 100% crop. Images from cameras 18, 21 and 24mp….as well as high end back are particularly unforgiving to poor technique. In other words, they will show every flaw in the technique of the photographer as well as the lens.
I have found that most complaints on the 7D originate from people who have not used high pixel count cameras in the past….but instead have moved up from 10 and 12mp cameras that are far more forgiving in not exposing the bad techniques of the photographer testing the gear.
Amazingly, once the technique of the photographers improve, you’ll find that in the future, they’ll obtain much better results from the camera….as though it miraculously healed itself.
