I was there yesterday for an interview. People that get put onto that list won't be hearing anything until UCSF has finished interviewing and had heard back from most of the people they accepted. Given that they still have a bunch of interviews left, plus the fact that it takes them a while to make the decisions, and then mail the decisions, and then hear back from the people they accepted.... You're probably looking at a couple of months.
But at least you're on the list. It could be worse.
