I agree with Stan. I don't think he is trying to denigrate people who prefer the 300s, I think he is responding to the numerous posts from 300/300s and d700/d3 users who are shrugging off the d7000 as an amateur's camera. It is one thing to point out it doesn't suit your needs, it is another to suggest that it is not capable of being considered a pros camera.
I also don't believe the ability to get 7-8 fps on a 300s with a grip (at an increased cost) is going to cause anyone to buy the 300s over a d7000 at a $400-500 premium given what appears to be a clear image quality advantage by the d7000 especially in the 1600-6400 ISO range (basing this now of the numerous test photos appearing on the internet). I can't really comment on the bigger body issue, I am in the camp that wants a smaller, lighter more potable camera. I carry my camera everywhere so bigger and heavier doesn't make any sense to me.
