Green Day Coming To Rock BandS

During Kevin and Bean's Breakfast with Green Day this morning on KROQ 106.7 FM, the band confirmed that they'll be doing something involving Rock Band in the near-ish future.

When an audience member asked them when their songs would be appearing in Rock Band, lead singer Billy Joe had the following to say: "Uh yeah, we're doing a whole Green Day Rock Band...uh." Uh? Is that a track pack, or a full game add-on? We've contacted Harmonix for more information, but until then all we have is "uh", along with this stunning revelation of the release date for "uh":

I'm not sure...soon. Like I think not this week, but this year soon...by the end of this year.

This of course leads us to the obvious question: how has Rock Band gotten away without having Green Day for this long?
