Just an FYI on Emory: they already had their finalist weekend in early February and have given out acceptances to those who were there and who made the first cut. The wait-list, from what I understand, is made up of those who were invited to the finalist weekend but who were not accepted in the first round. I don't know if they have anyone on the wait-list who was not part of that finalist group back in February. I don't know why they haven't sent out rejections to those they are certain will be rejected, but I had applied unsuccessfully to Emory before and did not get my rejection until pretty late in the game. In regards to the finalist weekend, I was one of those in attendance and have since been informed that I am on the wait-list after that first round of acceptances (I had to inquire as to my status after that weekend and was not notified of my status until I made the inquiry). I think they only had four spots this year, as they only give offers to those for whom they have funding.
Of course, don't lose hope and take this info with a grain of salt. I had not heard from some programs and had assumed I had been rejected because of the fact that I had not been invited to interview weekends and such, but then received offers anyway. I just had the info and thought you might like it shared. I sincerely wish you the best with either program.
