I most like will get this camera (to replace 10D as backup camera, next year) and I have tried to evaluate the image samples objectively.
My initial impressions about 20D image quality is that Canon has primarily sought after low noise and fine detail and so they have
a) lowered contrast (yes slight DR increase but also by internal shadow/hight processing just like shadow/highlight tool in PS)
b) made CMOS hardware noise reduction harder (or more coarse) on low detail areas
b) set up sharpening to touch only finer detail.
The overall look is ok but also has a sligh anomaly feel which can be described perhaps as "like using a slighly bad copy of a lens". Lens resolution vs. 1.6X (small chip trying to pull up lots of data from lens) surely adds to this problem. Or maybe that is the problem?
A visible examples of that

Same lens used.
In photo http://metasync.com/20d/pages/IMG_6930.htm you have fine detail here and there, but unevenly - exactly like after using Neat Image or such. And as a sunny day high contrast shot it lacks real contrast and definition.
