Who is opening for Fall Out Boy in their 2013 tour?

It starts in less than a week, but I haven't heard anything about who was going to open for them on tour. I got tickets so I was just wondering.

They haven't said yet. Rumors are saying Panic! At the Disco. They could have a polka band open and I'd be fine because I get to see them.
