I interviewed on the 15th and they said the admissions committee meets at the end of each month. I have read previously that a huge bunch of acceptances were issued march 6th of last year. I would assume that would be the case again this year.
be really really patient...i interviewed in early January and didn't get an acceptance till MAY! They totally lag so don't expect an email and check SDN like every 2 secondsl ike i did cause ur gonna go nuts...trust me most people in our class didn't interview till late and got there acceptance in like late April-late May...
