Hopefully you will hear something before you have to let other programs know! I am anxious to hear back as well; I only applied to UIC. I like the structure of their program, it's conducive to my work and home life.
Good luck to you, and congrats on the other programs!!
I emailed them a little more than a week ago and was told they are still reviewing applications and will notify applicants by the end of April. They had an increase in applications this year, so that seems to be slowing things down for the committee.
