I am currently on the waitlist as well. Spoke to Steven he said the people that were accepted have two weeks to respond. At that point they will begin calling people off of the waitlist. Its agonizing to wait but you're not alone. Just try not to be discouraged. The waitlist still means your application was very competitive but there are only a limited number of spots. I know when I was speaking to people before my interview, several had applied to multiple schools and some already had acceptances at other schools. So, that may open up some spaces if they accept positions elsewhere.
