Pretty solid response except that 60d body is NOT what it is advertised. I was just looking around since I am selling my 50d for a t2i (not stoked, but i need a second angle since ill be solo filming a lot this year), and I read a lot of critism on the body of the 60d. Its obviously a little bigger and heavier, but people are saying it is just like the t2i and they are disappointed on the durability. I guess there is a reason though that it is in between the t2i and the 7d though. Also as for the swivel screen, it is a good idea, but I read multiple concerns that it is very very weak and wouldnt pass the "drop test."
A good thing about the 60d is that you can control audio levels, but on the t2i you can not.
The 5d does not do 60p as you said, and I have not heard of any reasoning why? It has the dual digi processors, doesnt it? Just makes no sense.
Thats another difference. The 7d has dual digi processors (not sure on the 60d) and the t2i doesnt. The advantage that gives the 7d is that it does a little bit better in low light and can shoot stills at 8 fps vs the t2i's 3.7. Im not sure what the 60d shoots, but my 50d shoots 6.7 fps, so i assume thats the same.
If your looking to shoot stills only, you cant really beat the price of the 50d right now. It has a solid body (magnesium alloy), and the quality of pictures is some of the best for a cropped sensor camera.
On a side note, the t2i was actually tested and shoots a little sharper images then the 7d. Just something to think about.
Hope that helped a little.
