Hey, I got my waitlist notice on Mar. 23rd. I don't know if this really matters tho. I emailed the department today and they said that they are getting a lot of acceptance this year from the admitted students, which is obviously bad for the folks on the waitlists. They said that there is "some chance" that they will touch the waitlist at the end of this week. Oh, also, I tried to ask them about my rank on the list but they didn't answer me... anyway, I hope this helps and good luck to everyone on the list~
