I wouldn't get too discouraged. They could have rejected the application the first time around instead of postponed it, so they must have liked something! I also think they have a habit of postponing applications because I saw last year that individuals who wrote on their FB who got postponed now appear to be attending there. I don't think it means anything. I think they just do that to have the opportunity to grab any students who REALLY stand out that will mutually benefit IHEID by attending to try and persuade them to attend before the deadline to apply elsewhere. If the student can bring good connections to IHEID, then they might be very willing to extend an early offer. (That of course is speculation too). Either way. I just wish next week was over and I knew my fate.
Also, I have not heard back and I applied for a PhD program. It appears that they are probably pumping out decisions as quickly as they receive them back. Having worked at universities, in my experience it is very likely that applications are either trickling in from committees who decided to accept a student, or they got slammed all at once and are trying to catch up with the new database system. Who knows?! All I know is that hopefully the waiting will be over soon!
