With the introduction of the New Canon S410 and S500, when do you think the price of the Canon S400 will drop? Im considering on purchasing a S400, but dont want to buy it if the price drops all of a sudden. If it drops soon then I can wait until it does, but if its going to be a while then I'll purchase one now. I found one for $315 shipped from Dell Direct.(still is a great price, but I have to try and save when I can.) What do you guys think?
