Duke finally comes through for me with a ding. I assume that since 'most decisions are made by April 1' if you haven't gotten an e-mail from them accepting or waitlisting you, you might as well assume that you were rejected.
That being said, I really wanted my $82 rejection letter, and I got it yesterday. I love how they tell me that I must be "very disappointed," but well. Not really. Sorta. I wasted $82.
