The problem with the 60D, while its pretty good for video, is that it isnt a good deal for PHOTOS. Which is what these cameras primarily are. It doesnt have AF fine tune, etc etc etc....its really worse than the 50D in my opinion. So I think most people either spring for a T2i (if theyre main concern is video) or a 7D (if they like both video and photo).
I mean....why put a high megapixel high noise sensor in a camera they are pushing the video on?
If you like the sensor in the 7d, then you should like it fine in the 60d too, because from everything I've read they are identical sensors. The main difference is that the 7d has two sensors, allowing it to output to an HD monitor while shooting.
And why exactly isn't the 60d good for photos? Simply because it doesn't have the AF microtuning? Not sure I follow your logic.
