Wow! You mentioned that there were cameras in that video. I didn't even notice!
I'll be interested in comparing street prices for the 7D and D7000 when both are truly available side-by-side. I'm guessing the 7D will drop considerably. I don't think that 25% price advantage will manifest itself in real-world pricing. Probably closer to 15% ($1200 vs $1400 for the bodies).
WRT the high-ISO, I wonder if that was RAW or out of the camera JPEG? I'm gonna guess JPEG. RAW shots seem to level the field in my experience since you can apply much more sophisticated noise cancelling routines in post-processing. Nonetheless, that's impressive high-ISO performance from the D7000!
I remain disappointed in the video AF performance. I just don't get it. Why can't a DSLR implement decent contrast-detect AF, at least as capable as a $299 camcorder?!?!? And my goodness, how dumb can a subject tracking algorithm be that it loses track when a subject simply turns around? LOTS of room for improvement here, and an opportunity for Canon to do some leapfrogging in the 7DmkII.
No matter what, though, I think I'd choose the D7000 if I were starting from scratch. And man, what a great upgrade path for the D90 folks!
