I'm excited !
I've been waiting to purchase a new camera, I currently own and like my 40D, but sometimes miss not being to take video, also the ISO performance in some situation is an issue for me.
I like the crop body for the sport photography that I do, with my 70-200mm f/2.8 IS II lens and 1.4X III extender it is an excellent combination, so the FF are out of the question.
I've been tempted by the 7D in the past, but the 40D served me well, VERY well, I'll wait to see the first impressions from the reviews, but will not wait much before pushing the button I think, I think the 70D could very well be a very good camera for what I use, looking at the specs, for now of course

Cheers.
