I doubt it'll get cracked fast, Starforce on Spinter Cell Chaos Theory didn't get cracked for a year and that was not an internet-dependent form of DRM.

The draw of using the internet for DRM like that is that it's not just a phone home thing, it's that the game is probably made so that it can load its saves and such only over the internet, and it'll probably be very, very hard to crack unless the pirates can quite literally disassemble the game's code and write new routines for saving and such.
