Seems I'm one of the few who might get a 30D once the prices stabilise and the reviews are out. Agree 20D owners don't need to change. I want to compare one with a 350XT in terms of feel and ease of use. My current 300D is fine for most things, but the speed puts me off from shooting RAW as default and some of the other new features are very attractive.
To avoid hijacking the thread - its worth saying that if you have any trips to the US, or friends who are planning to visit from there, it generally works out cheaper to get kit there than here in HK. I got 2 of my lenses from B&H and Amazon delivered via my wife's business trips
