I've decided to get the 60D. The NEX-7, I've learned, can't do some of the types of photography that I had intended on learning, i.e. long exposure and time lapse. Plus, the lens selection sucked. I hadn't realized how much it sucked until I tried looking for alternatives to its kit lens.
I already know how to use a DSLR in full manual mode, especially the 60D because my cousin got one a few months ago (a waste, IMO; he's the kind of person who doesn't have the patience to learn the manual controls, and every time I've seen him use it I cringe because it's always in automatic). I always used my old SX10 IS in full manual mode, and even with the NEX-7, when I looked at it in the store, one of the biggest draws for me was the fact that, in some ways, it offered even finer manual control and more feedback information than the 60D did (the triple dials make it really easy to change exposure settings in full manual mode, and its buttons are very customizable).
So, anyway, 60D it is.
