I answered this on the other RWJ thread too: but no, I have heard nothing from them. I'm going to try to give them a call tomorrow (I left the card of the Admissions Officer at home). I'll let you know if I hear anything, but no response as of yet.
Best of luck to you too.
EDIT: I just called and was told that my application hasn't come up to the committee for review yet. I figure that since we were told that it would be somewhere between 4-6 weeks before we would hear, I'm just patiently waiting (you're lucky you heard so early!). And from what Dr. Terregino said, it seems like it depends on the committee, it's no reflection on you when they take so long to grant a decision. Congrats on your waitlist; I just hope that I'm so lucky as to make the chopping block as well.
