I asked the office today. The current projection is Tuesday, but obviously don't hold them to that. The MD/PhD decisions have already been made, but they aren't telling ANYONE until the med school releases their list and this is what they're waiting on.
I'll be impressed if it actually is Tuesday. In previous years they've been at least a few days, if not a few weeks, late pretty consistantly. I guess since they moved the decision date back from early -> mid -> now late march while not changing the interviews they're having an easier time meeting the deadline.
