I haven't gotten anything from Duke other than the phone call. They said they would send a mailing in the next 'week or so.'
When I asked about financial aid they said that the FAFSA wasn't due until May. I told her I'd already submitted it, but she didn't seem like they were in any rush to announce any scholarship info, which is frustrating, since it will be a big part of my decision.
I did post on the results page, so at least one of them is mine. With only a few people having posted here, though, I wouldn't lose hope! They don't seem to have many people in the admissions office, so I'm sure it takes them a while.
