I read up on the Canon 580EX II recently.
Amazingly, it appears to have a thyristor sensor on the front. If this is true, that would make it very flexible in being able to use it either in TTL or Auto mode (like the Metz's).
I haven't shot with it, and I sincerely hope many of the problems have been fixed since the 580EX....mainly exposure fluctations.
If the 580EX worked as I always felt it should, there wouldn't have been a need for a "II" version.
(never could get it to work consistently with any D series Canon body with the exception of the 5D).
I'm not anti-Canon.
I'm anti-"this doesn't work with that".

Everything Metz's will do wirelessly, Canon's will do, and visa versa.
Canon uses wireless TTL, Metz's use self-metering thyristor.
(Same result, just different approaches). If the new Canon flash does indeed have a thyristor based sensor, that would make it an appealing choice.
The Metz will require the use of a radio slave for off camera work, the Canon's is built in.
On the other end of the stick, Metz's can be used in the same manner with
all manufacture's bodies, not just Canon.
A dissadvantage of the Canon is the lack of wink flash...a feature I've found to be invalueable.
