I emailed the department and they told me:
"Thank you for your email. At this point all successful applicants have received Offers of Admission and wait listed candidates have been informed they are on the waitlist.
Unfortunately, if you have not received one of these items, then you will be receiving a refusal. Due to the large number of applications received it will take a while longer to issue the final refusal notifications."
I guess that means trying again next year
