That's what ex Sabbath Bassist Geezer Butler just recently stated in an interview with AOL's Noisecreep.

Ex Sabbath Bassist Geezer Butler says don't expect a Sabbath reunion with Ozzy anytime soon.  In fact in his interview with AOL's Noisecreep he said it probably wouldn't even be considered until sometime in 2012 (hopefully before the world ends).

He also recounts his final time with the late Ronnie James Dio who he was most recently in Heaven and Hell with.
