I was wait-listed at Michigan. I received a phone call from one of the professors a couple weeks ago and an official letter a week later. I haven't heard anything since though! I also applied to Notre Dame and the U of Chicago and haven't heard anything, so I assume those are rejections!
I've been shamelessly reading all of these posts and staying quiet until now, but I also got into NW and wanted to say hi! When are you going to visit? I'll be there March 2-4.
