There was a blog post by the dean of admissions January 2 that said they deferred an unusually large number of students (about 400) ED1–>RD because of the new SAT. That blog post was taken down at some point between Mid January and now. Someone one CC has the text of it in a posting. Judging from the number of people that just said they were deferred ED2–>RD, I’d say a lot of people were deferred. I have no idea what it means for chances at eventual acceptance. In January, I had emailed admissions and asked and they couldn’t give me an answer.
