My POI told me that six people are going to be guaranteed funding for one year (after that you have to reapply). I don't think funding info will come until the official letter though.
I'm one of them! I'm honestly very surprised I got more than one acceptance, but I'm not complaining. I think they made at least seven offers, so I'd think there might a few other people around here who got in.
I'm the person who posted the rejection from Columbia today, and the email I got said they had just recently made their final decisions, so there won't be any more interviews probably. That said, I have no idea whether they only accept candidates who had interviews.
The Buffalo admittance was me! I wasn't actually sure if it would be helpful to post or not as I'm a somewhat nontraditional student, but it seemed like a good idea given how much great advice I found in the forums when applying.
