One major bummer in the 20D is the shorter burst when shooting RAW, only 6 frames vs. 9 with 10D. I couldn't care less about speed with JPEGs.
OTOH, dpreview reports they got 36 frames at 5 fps rather than the advertised 23, using fine JPEG with 1GB SanDisk Ultra II card. That suggests the 20D has significantly faster CF write speed than the 10D, and that could offset the shorter burst length - actually I don't really care as much whether I can shoot more than 6 frames at full speed than about being able to shoot several short bursts without waiting too much in between. The slow CF writing speed of the 10D is a major pain.
Firstly, if you need speed, there's always the 1D Mark II. Secondly, there seems to be a trend of shooting less and less in RAW and more in JPEG. I have no hard data, it's just my impression of reading numerous web sites, forums and mailing lists.
The specs of the 20D, and the market they are trying to reach with it, makes a lot of sense.
What no-one seems to have mentioned is that the 20D does not have spot-metering (not surprising, though), but then again, maybe this was more of an issue on film SLRs.
