It's only one season away from being able to be syndicated, so the studio has a vested interest in keeping it going a little bit longer. In all likelihood, the show won't get cancelled, but the 4th season will get shelved until they cancel something else and need a replacement (much like CBS does with Rules of Engagement, which has inexplicably been on for 7 seasons now).
