I can respect their artistic integrity, I admire it even; however, this will have huge repercussions in the Rock Band world as the chance that Pink Floyd will ever be made available on a disc is incredibly slim if this is the band's official stance. They would be a huge get for Harmonix, a huge get, which means that now Harmonix needs to funnel all its effort into the last big hold out from the music and rhythm game genre: Led Zeppelin, which will be incredibly difficult given their public stance on the genre. I would say there is a chance that they could be made available as DLC in a full album release, but full albums on the Music Store also allow for individual downloads. I suppose there is the chance a track pack, ala AC/DC will be released, but I would doubt such an event highly.
