From the FAQ on their department website:
"We start reviewing applications in late October or early November. Admissions decisions may be made on a rolling basis as applications are received, so there may be an advantage to applying early."
It doesn't sound as definitive as I remembered but they mention it in a couple other questions too. In any case, it doesn't really seem like they really have rolling admissions.
