Putting their legal matters now behind them could open the door for another reunion.  Iommi recently told Britain's "Sunday Mercury" that he and Osbourne briefly spoke after the death of former Black Sabbath and Heaven And Hell singer Ronnie James Dio, and they agreed to talk further in the near future.  But Iommi also admitted, quote, "It's weird with me and Ozzy," noting they have a "complicated," on and off relationship.  However, he added that they have, quote, "always kept in touch, no matter what else might have been going on."  Immediately ahead for Iommi is Heaven And Hell's performance in honor of Dio, which is coming up Saturday at the High Voltage festival in London.  Iommi explained that he's currently focused on the weekend show, so regarding Ozzy, quote, "once the tribute is done, we can all sit down and decide what it is exactly that we'd like to do."
