In at MIT, wait list for funding. Received a letter (FedEx) today. Letter was mailed yesterday, so it might take another day to arrive depending on where you live (I live in Boston). 360 applicants, 7% accepted.
I received an email from a prof in my subfield yesterday. This afternoon I received a form email saying a decision had been posted on the Yale application site, which then led to an official acceptance letter.
I can claim one of the Yale acceptances. Email from a prof in my subfield. Arrived a few hours after the first one that was claimed on the results page, so they were definitely not sent at the same time.
