When was your interview? As of the middle of january they had 100 or so deposits for the 124 seats in the class, not counting the interviews that day. If your interview was after that your prob on hold because they don't have anymore seats to offer. If you give Mike Robertson a call in admissions he will be able to tell you how many deposits are received.
Once accepted you are given 3 weeks (two week extension possible) to make your decision, after that they withdraw their offer in order to offer seats to those put on hold. But.....SCO refunds 400 of the 500 dollar deposit if you change your mind before April. Some students still debating other schools with later deadlines may wait until then.
So, they will regularly be getting seats opened as people make their final decisions.. I wouldn't worry til around april or may when desicions become more final. Even then, I've heard of people being told of acceptance in August.
