Looks like 40D will be discontinued pretty soon and some Canon dealers are really slashing their prices. I've been thinking about upgrading my 400D to 500D (or wait a few months for 60D...) but now it's actually cheaper to get a 40D than 500D (in Australia anyway), would it be a wise move to buy 40D instead of the new 500D (and no, I don't care about any video capabilities)?
