Looks like I kind of get my wish. Short version: U2 will have a companion album for No Line on the Horizon out later this year.
I imagine it will kind of be like how Coldplay put out Viva La Vida and then Prospekt March. Only hopefully BIGGER.
Okay...this year, I've gotten a new Springsteen album and a new U2 album. On the horizon (heh) I see a new Pearl Jam, a new Ben Harper, and yet another new U2 album. Seriously. This year kicks ass.
