Just jumping in on all the speculation of why it takes so long since the meeting for decisions to be sent out. And yes, they have been made. The lag is due to a personal screening by the Dean of Admissions of each accepted applicant.
As mentioned previously, there are several small subcommitees that review the MD application pool. Once they have reviewed the applications they are responsible for, all applicants selected for admission are forwarded to the Dean, who then personally reviews every single file before giving the final approval. This takes time.
On a different note, MD/PhD is reviewed by a different committee (some common members), and PhD is yet another committee. I'm not completely sure on this, but quite certain that only some of the MD/PhD and PhD decisions have been made. Note that at least the PhD interviews are still ongoing although MD/PhD is complete.
Anyway, hope that helps [at least in part] why there is such a long lag... good luck to everyone! 🙂
