I don't think anybody is remotely close to doing rejections yet, it's not even the deadline at the vast majority. Alot of the programs I'd talked to hadn't even looked at any part of the apps yet, and I would guess the ones that have offered will send out plenty more invites.
That said,
Indiana University by snail mail for Dec 1st, 5th, 8th or 12th with dinner the night before.
