Even according to DxO the SNR difference is negligible in real world photos. Then add the additional 4 MP to help with cropping. You might not want to believe it's a D3 killer, but for my money it is, and without pixel peeping I seriously doubt anyone could say otherwise, especially after post processing. So much nowadays comes down to the individual's skill set with PP tools,.....and then there is that little thing called art.
As for Ken, he's an outspoken and popular Nikon DSLR shooter/reviewer with a very successful website that has used all the gear. These people all have their critics and I also read DP and the other sites. Keep in mind that he only uses Nikon DSLR's for personal use. To me that's a pretty big advantage in reporting the ins and out of camera gear.
Well at the end of the day this is the camera that best fits my budget, and in many ways it compares to or betters the very expensive D3 so I'm pretty excited about it!
Oh and for the record, if I could afford it I'd wait for the next Nikon FX, but sadly that's not the case.
