I didn't get much more info from USC unfortunately. The department is constrained by a policy of how to make offers and hopes to change this in the coming years. The visit day itself was great: the potential cohort had a great feel, the campus was beautiful, and the professors/current students were very relaxed and amicable in a way that felt authentic. Most of the people we met with are relatively new hires, so the department seems to have a strong upward trajectory. I would say, unfortunately for those who haven't heard yet, that USC definitely helped their potential yield rate a lot. If you get the offer it would be a great place to attend. If you have other offers but really want to go, I would email Jeff Nugent and ask him directly if you should keep waiting to hear something. They don't seem to have rejected anyone yet, so unfortunately hearing nothing at this point likely means IR. However, some people (who haven't heard) will invariably be closer to getting an offer than others, so it doesn't hurt to reach out.
