I emailed UNC recently (about GRE scores) and they said decisions were still being made. That's one of my top choices so I'm hoping it turns out well.
Haven't heard anything from Boulder though.
I applied to Michigan and Illinois. I have the same awaiting decision thing. Based on results here from past years, I think I've given up on UIUC, but hopefully Michigan still has some acceptances to send.
I haven't emailed them yet (I'm not 100% sure if I will), but my application page says the same thing as yours. I've also been checking wolverine access, but that doesn't have anything new since I first submitted. If I do end up emailing, I will let you know what they say.
