That was me! Lol. I don't know if they sent out any other acceptances or not, but basically I was told that my file was looked at among the first group because my undergrad institution just hired one of their PhDs a couple weeks ago. They then evaluated my app and liked it enough. I should point out that they were trying to fill more spots this year for the major area I applied to because there was a shortage in that area for the last two years. I'd be willing to bet that they're trying to admit people who are very likely to attend as well. My SOP pointed out a very niche methods topic in which UIUC has 3 experienced professors publishing, so I am most likely going to attend because of this.
