I think in the end it doesn't matter. From what I've read in the past, the Admissions Office likes to keep the percentage of EA and RD acceptances around the same.
...Although after reading the article, I do wonder if the 350 applicants who opt out in the EA round (because they were accepted ED somewhere else) somehow help the other EA applicants. Do they possibly give applicants a spot, who may have been put in the possible RD pile?
Applications are still being completed (Sandy slowed things down for folks up north). The numbers I have (again, which are still moving) aren't at 14,000. I think the number will be lower than that. The dean was giving a group of colleagues a status update, not final data that was ready for publication.
EA schools always have some students pull their applications after getting in elsewhere ED. I don't think that's anything that should be causing any of you worry.
