I have to assume the handful of people left are on the border of waitlist and admit and are being re-reviewed for a final decision. I doubt they would spend too much time analyzing between a waitlist or ding (why not just waitlist then?) and I doubt they just haven't had a chance to get to ours at the bottom of the pile (btw I interviewed back in November), so I believe of those of us left some will get a call/status update to admit and some will get waitlisted. Since we are not part of the big wave of decisions, the status change can come at any time, not necessarily at 3am anymore, as others have reported over the last few days.
Unfortunately this is making me even more crazy as I now am checking my status multiple times a day instead of just when I wake up in the morning

I still don't think there have been any confirmed status changes other than very early morning. People have just reported on here at different times.
