Ha, I can't believe they keep pumping out music. Siren Song and Revolutions are among my all-time favorite albums but when they switched to radio rock I gave up. Appeal to Reason was mediocre, but Endgame was truly dreadful.
I love how people describe Rise Against as "radio rock" because I honestly can't think of another band on the radio who plays music like they do. They're more melodic than they used to be but they're still putting out great music.
Incidentally, they also released a new teaser clip of some songs on the website, including one very hardcore-influenced one (complete with screams).
