Just emailed Stanford psychology admission and they said all of the interview invites have been sent out:
"At this point, the faculty have extended invitations for candidates who were selected to participate in our interview weekend. You have not progressed to the interview stage at this time. I imagine that this will be disappointing news.
Please note that final admissions decisions have not been made, and occasionally the faculty seek to interview additional candidates through separate mechanisms. This is the reason that we do not send out formal admissions decisions to candidates who are not invited to participate in the first round of interviews. That said, historically speaking, such additional interviews are rare."
