I was not awarded either time that I applied the last two years. My packets containing rejection letters and reviews were dated April 29, 2011 (Very Good, Very Good, and Very Good overall scores) and April 12, 2012 (Good, Excellent, and Good overall scores). These were external reviews, and I believe that applications that pass this stage get sent to internal review, which explains why notification could take longer for students that are awarded.
So, I would expect a packet in the mail in the next 3-4 weeks if rejected. I don't remember from the past forums when people found out that they were getting the fellowship, but I think they were notified by phone. I just hope I don't see another packet in my mailbox this year...
