Another Systematics person here.
My French is very good and just needs some brushing up. I will have to learn German this summer or during my program at some point.
I also have a little bit of Koine Greek but that was back in undergrad.
I would say from my very limited experience that it's probably a good idea to have at least one of your languages done by the time you apply.
To the person who said Marquette had 4 funded spots, was that in the entire Theology department or a particular subfield (e.g. Systematics)? Also, how do you know?
I was one of the people who got wait listed at Loyola University Chicago. My email was identical to the one a previous user copy-pasted here (except with my name, of course). Seems a little disingenuous to send that to more than one person!
