Judge for yourself guys.
Seeing its dark. It most certainly beats a 7D, match for a MkII? Close, will have to see more. Wow from a consumer camera
ISO 3200? We can get that w/ NR set to standard or high. What's so great about that photo? Color's flat, details seem muted. It doesn't look any better/worse than most digital camera photos. I don't get it. It's shot at f/4.0, 1/40s, iso 3200. I do not consider that dark. Dark/low-light to me is when you're shooting f/1.4, 1/40s, iso 3200 (which is 3-stops less light). With a f/1.4 lens, that means you can shoot that same photo (neglect the DoF concerns) at f/1.4, 1/80s, iso800. That's not too tough, IMO.
Wait for the actual reviewers like DPReview and other sites before getting all bent out of shape just because Chase Jarvis and team posted up some JPGs. You want to see clean high ISO shots? See here:
f/2.8, 1/50s, iso6400 (My lighting is nearly 2-stops dimmer than the van shot.)
No doubt the D7k is going to be a very competitive product and will rightly draw lots of attention. But you're harping on it as if it's the 2nd coming of Jesus.
