i was waitlisted and finally got in this week. regarding this year, just try to update them with letters and call around once a week (worked for me). as far as applying for this year, i just sent them my committee letter, which included 2 bio, 1 psych, and 1 history letter of rec (i was a bio/psych major). so i would go with that, but it wouldn't hurt to call them again as specifics may change year to year.
