I think they actually haven't made decisions on all their applications. It seems like they were just sitting on some applications until the seat deposit deadline. I applied in January and only after I called an asked if their class was full did they change my status and send a waitlist notification. I am a borderline applicant, so I think they may have been waiting to see what their class looked like before making a decision.
They're probably doing things a little differently this year because they're reducing their class size. Who knows.
My only hope is that decisions for waitlisted people come soon.
