Starcraft 2 got its always-online cracked, as did most of the Ubisoft titles forcing it like Assassins Creed 2. I think the only example without good cracks is Diablo 3, and I know if I was a game cracker I wouldn't even bother, just because D3 sucked for me.
I imagine SimCity has enough publicity the warez crowd is jumping all over the opportunity to be first to crack it. People I know that have played it called BS on all the allegations that anything critical to the game running is server side, because the servers can go down while they are playing and they only lose saves and achievements.
Eventually someone will get around to reverse-engineering it. One good recent example is Diablo III, which had a semi-working emulator (most of the content was not yet implemented) by the time retail was released, but was shutdown following a C&D from Blizzard.

From what I've seen, it's certainly a possibility. I'm not sure how it works but I know that a fake server would be used. This has been done for another game http://torrentfreak.com/ubisofts-uber-drm-cracked-within-a-d...
It's a bit of a different type of game, Diablo 2-esque, but if anyone hasn't tried Path of Exile, I suggest it. A small, independent studio just launched much more smoothly than EA can, is pretty good about how they treat players and is adding content weekly.
