Apparently the 40D release will be soon. From rumors at least, the most 'reliable' are saying sometime this September. I was planning on upgrading to the 30D this month, and as I was looking around, I started hearing about the 40D. When the 40D model comes out, will the 30D price drop? I mean, I know nobody knows.... but when the 30D came out, did the 20D price drop? I imagine there will be quite a price difference between the two, so i'll probably get the 30D, but maybe I can save a hundred or two by waiting... any ideas?
