Sorry I'm so late in replying, but this website wasn't working for me for several days.
The other (besides UVA) schools I was considering were Brown, HDS (as backup), Princeton (Religion, not TS), Indiana, and UChicago.
I'm not positive why they're taking so long this year. Last time I spoke with the DoGS, he seemed very busy and stressed out, and said that they were harassing their prospective admits a lot, trying to get them to pick UVA definitively. Chances are that they've sent their first line of acceptance letters out and are slow-rolling some of the waitlists and rejections until they know who's accepting. They won't have much money next year (this is a rumor, not definitive) to offer incoming Ph.D. students, so I imagine they expect a lot of their first picks to accept at institutions who can fund them better, and they don't want to reject too many people until they hear back from them (in case they need to expand the waitlist).
THIS IS ALL CONJECTURE, THOUGH, so don't go slitting your wrists or anything.
