Looks like it has taken another twist:
"After news yesterday that Black Sabbath were reforming, Tony Iommi published a statement which suggested the claims were unfounded. However, Ultimate Guitar can confirm that a Black Sabbath reunion is still a possibility, and that they’ve probably been writing new material for months. The story began when Metal Talk claimed that the band were reforming and were due to begin rehearsals yesterday. Evidence seemed thin on the ground, but then a Birmingham Mail journalist, Andy Coleman, seemed to confirm the rumour when he quoted a conversation with Iommi from June.
"We’re really looking forward to it and I think the stuff we’ve been writing is really good," Iommi said. "It’s all been very hush-hush."
Today, the Black Sabbath guitarist appeared to quash the story in a statement on his website: "I'm saddened that a Birmingham journalist whom I trusted has chosen this point in time to take a conversation we had back in June and make it sound like we spoke yesterday about a Black Sabbath reunion. "I hope he's enjoyed his moment of glory, he won't have another at my expense." As a result, the majority of the music press reported today that the rumours were false. But we couldn’t help but notice that Iommi doesn’t deny the reunion.
Today, the Birmingham Mail confirmed this by posting a conversation with Iommi’s manager, Ralph Baker, which suggests the idea of a Black Sabbath reunion are still alive. It seems Iommi acknowledges that he never denied a reunion, or the statemenets he made in June. "We haven’t got anything in place," said Baker. "He’s not denying that the guys have been talking," before rudely adding "A very insignificant little website [Metal Talk] put something out about Sabbath getting back together and being in the Midlands." Apparantly, Iommi was upset that the Birmingham Mail gave weight to the Metal Talk story. "That’s why Tony’s p----d off, because the story would have died a death."
Speaking to UG, Andy Coleman said he was only confirming the story after the reunion first leaked on Metal Talk, but the Iommi statement had given him a busy day. Why reveal Iommi’s comments now, and not before? "Once a story is out there, it’s out there," Coleman said. So the question is, are Back Sabbath reforming? Iommi hasn’t denied it, and even said that the band had written new material. All he said today was that he was disappointed in a journalist for publishing what he felt was an off-record conversation. So ignore the reports on other metal sites today - Black Sabbath have written new material, and are seriously considering a reformation. Rock on!"
