@hami9293: Although I do think they are only pending applications, I think it is more than 'just the last applications' to be reviewed. And I am not being optimistic. I think most decisions were made late-February, early-March, when most admits/rejects were sent out, the borderline cases left out for further debate within the admissions committee. There has been no activity since early-March (at least on gradcafe, except maybe a couple of posts), which wouldn't be the case if they were merely reviewing the applications, and there still were clear admits/rejects in the pile. They also wouldn't have kept the applicants waiting if there were easy decisions to make.
Well, this is just my understanding of the situation.
