Any time a veteran band returns from a long hiatus with a new album, fans hope it means they're back on track creatively and ready to follow up with another record sooner than later. But rather than the start of a new chapter, it looks like Black Sabbath's '13' could wind up serving as the group's swan song.

Echoing comments they made several weeks ago in a recent issue of Revolver, Sabbath members Geezer Butler, Tony Iommi and Ozzy Osbourne shrugged off talk of a new album during their latest interview with Classic Rock Magazine, offering responses ranging from the non-committal to the downright gloomy.

"We've not spoken about it, to be honest," Iommi said in the interview. "I don't know if it would be the right thing to do. God knows what the expectations would be next time around. I'd probably have a heart attack worrying about it! Making '13' was such a great, memorable experience, so if that's the final chapter, we'd have to be happy. But who knows. I don't think we'd write anything off. The history of this band has taught me to never say never."

"We'll see what happens," added Osbourne. "We made promises about another album 15 or 20 years ago and it took this long for it to happen. I don't think you'll see another one in 20 years, put it that way."

As far as Butler seems to see it, however, the band might as well be finished. "To me, it's been nicely rounded off now," he mused. "If we did another album, it just wouldn't have the same vibe, as far as I'm concerned. And with this one doing so well, the next one would have to be No. 1 everywhere too or people would see it as a failure!"

Released in June, '13' gave Black Sabbath their first-ever No. 1 album in the U.S., with roughly a quarter of a million copies sold in its first month on the charts.
