Brendan just put a new update on their official site. It says:
"We were sitting around the other day, just farting on each other as gentlemen of our unique social position are known to do during long van rides when we realized that we are all pretty tired, and pretty burned out on never being at home, so we decided that after our upcoming tour with Tsunami Bomb (which will be a US tour in July and August) we are going on hiatus, or, for the less verbose of you, taking a long break. NOW, don't freak out or anything, we are NOT breaking up or any crap like that. The website will continue to be updated and we will continue to write songs and shit like that. Hell, we might even do some shows around Chicago, but we ARE going to stop touring for a while."
Hopefully their break won't be too long.
You can check out an interview with Brendan and a review of their past record while you're waiting for the hiatus to end.
