Without getting too technical, what concerned me about some of the photos in the thread I linked too was more of a subjective sense that shot sloppily and/or post processed indifferently the D7000 can show some noise. But no biggee that was just one data point among dozens available on the web now.
My cam arrives this week and I am still looking forward to it. My sense not based on any experience yet is the D7000 will still require some shot discipline and care in PP just like I do now with my D300. I expect it to be better in certain areas than the D300, areas important to me so that is why I ordered it.
For context even when I goof up badly my D700 has a little more special sauce to come to the rescue and it looks pretty promising that the D7000 sits midway between the D300 and D700 in that respect. A significant achievement that I impatiently await
