I was there in mid January and it took about 3 weeks, but thats just because they wanted to wait until Feb 1 to mail my letter. I think they said the committee meets every 2 weeks to make their decisions and they mail out quickly after that. I would expect the 2-3 week window. Dont bother calling, they wont tell you anything over the phone.
If you get in, be ready to put down that $1500 deposit. they dont skrew around when it comes to paying!
I am really curious as to how many seats are left also!
