So I called the graduate department, and the woman informed me that all decisions (acceptances, rejections, waitlists) are going in one mass e-mail next week (she suggested I start checking my email regularly, as if I haven't been doing so pathologically for the past six weeks). She also stated that no "informal" decisions have been made to anyone, although I really do not doubt the credibility of the few claims to such on this message board so far. Good luck to all.
