I'm a 4th year at Maryland and have been involved in the interviewing process. From what Dr. Meehan has been saying, I have a feeling that offers may be slower in trickling in until those who have already been offered respond. Just hang in there for a month or so if you've already interviewed. If you haven't heard by then, send an email over to Dr. Meehan. She's very receptive and will at the very least give you a heads up. Good luck to everyone!
