In addition to what was mentioned by sleepyS4, the new autofocus system on the 7D is nice as well. It's fast. There are several different types of selective AF modes to play with so it not only makes the focusing easier and faster but tracking as well.

And I'm currently shooting a 7D with
24-70 2.8L
70-200 2.8L
100 2.8 macro
kit lens

But I want to invest in more primes.
