I found this:

It is the Emory Common Data Set 2007-2008, which is this year's data isn't it? It has the number of wait list admits already filled in. However, the number of people who accepted a place of the wait list is exactly 800 for the previous 3 datasets as well, which seems suspicious to me. Can anyone verify the validity of this?
