This is a good question. I'm guessing the former, seeing the way the news is filtering through. Though it's hard to be sure. Also I note that everyone who's been admitted so far has been an American applicant- different system for internationals, or is this just wishful thinking? A sample of 5 can't tell us much, admittedly, but still.
Last year people were admitted over the course of several days.
So if I haven't heard anything by this evening, I'm going to assume I'm not in - but with a healthy dose of equivocation!
