I have to say, I'm not overly impressed with Westfall's interview.
I found his response to the question about high ISO performance with RAW files more than a bit unsatisfying:
"These figures are not being disclosed, but of course they will be lower than the noise reduction achieved with in-camera JPEGs and EOS Movies."
It sounds like the camera has a great autofocus system and I know that's what most 5D II people wanted, but as a 7D owner hoping for improvements in sensor technology, his comments aren't giving me a lot of confidence.
