I haven't heard back too.. but they had sent out this mail when notifying that my application was complete which said:
"The Admissions Committee will be reviewing files throughout January and will start sending notices on a rolling basis to applicants beginning in February. However, decisions on admission and rejection will continue to be made until mid-April. Every applicant will receive an email notification of either admission or rejection by the end of this period."
So, you can only wait and hope for the best till mid-April!
