It sucks to hear that about Chicago as I am an alumni. I also haven't heard from Columbia but I've been putting that up to the fact I live overseas but I haven't gotten any emails from them except for an invitation to attend an event a masters program was putting on . At least I got a good offer from Maryland.
I'm China right now so I have to wait for the Chinese to go through my mail first so that adds two weeks of anxiety. I appreciated the email rejections because then I could get over the angst in one day.
