Jimmy Chamberlin wrote on the Pumpkins official blog that the band will not record another album on CD. But he claims that the band will never break up and always will be making music, just not on CD’s you buy at the record stores. Sounds to me the band will release songs in mp3’s similar to what Nine Inch Nails and Radiohead has done.

Don’t worry, Billy and Jimmy will release another Pumpkins CD down the road again although they claim they won’t.
