I'm not going to claim I know much or anything about the deferral list other than I was accepted off it last Wednesday (by phone call). I went into the admissions office the next morning and the women I spoke with mentioned I was one of the first to come off it. However I believe they re-reviewed everyone who was deferred at the weekly adcom meetings. I interviewed really late and was immediately deferred...
I know that's not much information, but I hope it helps. I would say emailing your questions wouldn't hurt.
Best of luck to you
