Have you tried calling them L543? I saw that someone contacted them a week ago and was told they were waitlisted.
Also, someone told me last week that Wisc admits a couple people after the first visit weekend (which is this weekend), but I do not know the accuracy of that statement.
ETA at this point: I've gotten two rejections (Stanford, Yale) and haven't heard back from two schools (Wisconsin, Penn). Someone told me two months ago that Penn was on the fence with my application, so I'm assuming a waitlist at this point.
