I happy about the improved extended burst rate and the manual audio recording controls. I could have used the extended burst mode earlier this spring with photographing batters at ballgames.
What I would appreciate from Canon is a loyalty program similar to loyalty programs offered by automotive companies like Toyota or Ford. When it comes time to upgrade, a loyalty program could offer exclusive rebates on new camera bodies for existing registered Canon owners. It would make upgrading less painful. Just my IMHO.
