There's still nothing concrete on the Bohab grapevine, but the rest of the band seems keen to keep making music. The original Beefcake is coming back to sing vocals for a fall tour, and they're talking about recording more stuff; dunno if it's going to be under the GWAR name, or if they'll start a new project, but it does not appear to be the end of either the band or the GWAR-B-Q.
Brockie was always pretty adamant that GWAR is the characters and not the people necessarily, so he had always said he wanted the band to continue down through the years with new people taking over as people quit or died or whatever.
