I talked to another person in admissions, and they confirmed that I was in fact waitlisted, and that everyone should hear within 48 hours via email ( I talked to them yesterday).
What they also said was that the wait list was not in any type of priority order, and that they were going to wait until April 30 and at that point they would assess how many spots they had available and then contact the wait listed people to see if they were still interested, etc. The incoming class is maxed out at 45 people, and they wouldn't tell me how many they accepted, and how many were waitlisted, but they did say that over 600 applied.
