I like those specs..
D7K AF and Metering? That's a nice upgrade!
The increase in MP count is not as bad as it sounds for noise, whilst pixel noise increases, the actual image noise stays roughly the same for similar generation sensors.. so you won't be any worse off at high ISO, but you will gain resolution at low ISO..
The only other downside is a slight drop in DR, but nothing dramatic..
Not sure what they will do with the D7K, surely that's overdue a revamp?
I wish they'd do 1080p60 not 1080i60 for video, and nikon aren't quite there with video AF IIRC, so be interesting to see how it pans out
