"The fans have been wanting to see this for years and years. Now was just the time," publicist Maureen O'Connor said Wednesday.
Original Sabbath vocalist Ozzy Osbourne said in a statement that he wished Iommi and Dio well, and he made it clear there was still only one Black Sabbath.
"Tony Iommi and Ronnie Dio are working on a project together which has nothing to do with Black Sabbath. There is only one Black Sabbath," Osbourne said in the statement released by publicist Lathum Nelson.
"Ozzy, Tony, Geezer and Bill will be touring late next year along with a new Black Sabbath album," Nelson said. "However, Ozzy wishes Tony and Ronnie much success in their project together."
Since its formation in 1969, Black Sabbath has undergone numerous member changes and reunions.
Dio, who replaced Osbourne as part of the band's early '80s lineup, has been recording new songs with Iommi in England, O'Connor said.
