I was at a local camera store recently and a customer with a 40D was talking to a Canon rep about upgrading to a 50D. The rep stated that the difference between those two models was not all that significant and he would be much better off waiting a few more months for the 60D. Since that is all of the information that he volunteered, I suppose that it will be up to me to fill in the gaps with idle speculation. For starters, the performance specifications of the 1Ds III along with faster processors, wider ISO range, live view, and full HD video at the same price as the 50D would be good.
