Hi David, you are right that the D400 will likely be good but do not expect it to have better IQ or lower noise. The difference between the D300 and D90 was in details of use, not basic image capture. Expect a better AF version of the CAM4800 that the D7000 has, expect better video in respect to frame rate at 1080p at 30fps, wider bracketing, more dedicated controls and better weather sealing. The new processor in the D7000 is supposed to be a lot faster and wider in data path, and at the beginning of its refinement path. There is enough horsepower in it to process 14 bit images faster, so if the buffer is greatly increased expect longer sequences of higher frame rates. Apparently the D7000 does well in processing full 14 bit images. I doubt pixel count will be much different than the D7000 like the D90<>D300 shared a lot of specs.
It will surely cost more than the D300s did when it came out.
