well this is my gripe about canon, there isn't a cam that has more features than the d7000 in their mid range line, so far all we have from canon is a 60d and now the 600d, so i feel the closet thing would be the 7d.
im wandering if many canon owners who have budget-mid slrs actually decided to switch to nikon d7000 due its many features.
The d7000 is right between the 60d and 7d in performance, and price.
If you already shoot Canon, why wouldn't you just spend the extra $250 over the d7000 and get higher resolution, higher FPS in jpeg, much higher FPS in raw, better video, better AF, full magnesium body. The only advantage of the d7000 is dual memory slots, but they're only SD not CF (or ideally one of each).
On the other side of the coin though, if you already shoot Nikon, the d7000 is close enough to the 7d it would be silly to switch unless there are other considerations.
