What should I do if I interviewed for a job and just got an email saying I'm one of three finalists?

The interviewer told me that he and his team are going to deliberate this week and decide by the end of the week. I replied to his email and thanked him and his team for their team, re-expressed my interest, and restated my qualifications. Is there anything else that I can do? I don't know anyone who knows him or anything like that, so I can't have anyone call for me, but any other ideas would be appreciated. Thanks all.
