I feel there are plenty of people in the market for crop sensors. some of us just don't have the money to leap to FF, others want the reach, and I'm sure there are others who have other reasons.
Personally, I don't consider the 60D or 7D cheap with my budget, so I am holding out for a 7D2 or a 70D with features like the 7D (micro adjust, AF and 2 axis level being the big items for me). My Budget could allow for a 5D2 at the current prices but not any adequate glass to go with it, plus I don't like the idea of spending so much money on something that will in all likelihood be replaced soon (personal preference, the 5D2 is still a wonderful camera).
