Nope, haven't heard back from them since the day I was notified. I don't expect much from PSU since the email I received doesn't sound very optimistic...
"I need to inform you that there are others ahead of you on this waiting list..."
"Regrettably, there is a chance that we will not, in the end, be able to make you a funded offer..."
kev0476's email sounds a little more positive than mine. But I think I'll shoot them an email anyway.
I'm not sure what kind of grant my POI is waiting for but he did tell me that while he remains hopeful, there are possibilities that the application will fail, or something along that line.
I still have roughly a month to make up my mind though. Hopefully there will be more good news coming as things progress (I am still waiting to hear back from one more school).
