Looks like a nice little camera, the specs you guys mention above aqre all good, but I see the best advance over the 30D and 20D being the 14 bit color.
That should give really good color on high contrast situations like fish and tackle and as well should give better highlights.
Stuff I’ve seen from the 1DIII really pops and the noise at high ISO is the lowest of any camera on the market – some of that on the 40D would make it a great camera for the money.
Here’s some more info on them from the Poms.

I’ve ordered two of the new 1DS III’s just announced for my real work (non fishing) and shoould have them in November.
I’ll post some shots as soon from one when they get here…
