Did you apply PT, i haven't seen anyone report a decision who applied solely to PT, at least no acceptances, so I would figure the acceptances, if any, would be those.
I would argue that being wait listed is either much better or much worse than being deferred, but not equivalent. People in the past have spoken of a preferred or priority WL, so people got on that you would be almost assured of a spot. They also speak of the normal wait list which almost nobody seems to get off and the few that do not until very late July or Aug, so people who get suck there could be in for a long summer.
Why not call and find out for sure that they anticipated more acceptances this week, since this forum is mainly conjecture and BS? I only mention this because while the admissions people might be willing to comment "decisions" will go out, I doubt they would say acceptances. All of the offices I have ever spoken to were very careful not to release or discuss any info that has any bearing on anyone expect my own app, such as making a broad statement that more acceptances would go out. I would guess that the poster just put a positive spin on it or heard what he wanted to hear. I really doubt they would make such a broad generalization about acceptances since they have only ever seemed to talk about the time frame for decisions and not specifically rejections, acceptances, or deferrals.
