I haven't heard anything either, but it's still a bit early. That said, I applied for the pre-doctoral fellowship and based on grad cafe reports, last year around this time some classics pre-PhD kids got interview requests. I'm also worried about the fact that a poster on that other thread reported receiving an interview from this department and also said they're only accepting 5 graduate students this year. Princeton is a long shot for everyone, a near impossibility for me, and way way way tougher this year.
