Bono was on The Late Show With David Letterman Thursday night and Dave asked how the new U2 album is coming along. Bono didn't give any specifics, only saying that they "have to make a great U2 album" and their fans "don't care waiting as long as it's great."

There has been talk that it might be out this year, although nothing has been announced. U2's last album was 2009's No Line on the Horizon.
