Yeah, this certainly makes it more interesting (and distracting). I don't know how to discern what it means, but I keep telling myself that rejection is still quite likely: perhaps they simply sent out some rejections on Saturday and will send the rest tomorrow. The thing is, it appears that they are a week behind vis-a-vis last year's schedule. If it is actually the case that they are on the same schedule as last year, then more rejections should come out tomorrow along with a few acceptances, followed by more rejections around next weekend.
Maybe someone else has more info on this year's process? I know someone called the department last week and was told that all decisions would be finalized by last Friday (the 17th). If it is the case that everything has indeed been done, then they clearly are operating on a different schedule from last year.
