DPReview has some good details on Canon's new 20D. Overall, looks like a great update to the 10D. I'm not terribly tempted to upgrade, though, for a few reasons:

• It has an 8.2 megapixel sensor -- less than a 2 megapixel increase from the 10D. I think I'd be more tempted by a 50-100% increase.
• It isn't a full-frame sensor; still the same dimensions (1.6x crop).
• Still no spot meter (~9% center)
• 95% viewfinder coverage.
• Same small-ish LCD panel.

I think I'll hold out for more of the above.
