I had a regional interview in November and was accepted on December 1st. I declined my offer about 2 weeks ago, so my spot is now open.
Even though I had a regional interview, I still looked at the school when I was in Boston interviewing at Tufts (it didn't work out to do both interviews that trip and I didn't want to fly back). The school was okay, definitely not as nice as Tufts and a little more expensive. However, they do have a good program and Boston is a great city!
Keep waiting, I'm sure you'll hear from them.
