From what I understand, they'll send you an email even if you get pushed to a regular interview. So either way, I'd expect an email. Unless, of course, I was so far out of KU's interest that they had no interest in interviewing me at all, but I'm not sure as a Kansas resident that I would be THAT unattractive to them...
No you'll definitely get an e-mail. Last year I applied EDP, but was pushed to an RD interview. I didn't get my e-mail until a few days after the people that got EDP interviews though.
