Hm I looked on the board and it looks like sometimes they do, sometimes they don't. They might do them for some people and not others, depending on the applicant, but it seems to vary year to year. The person I know was talking about this year, but I might have misunderstood or something.
I looked at the board again, it does look like there are internal waitlists so some people are notified earlier, some on April 15. I wouldn't lose hope!
