This isn't selling out; it's returning to a formula that WORKS. You've all forgotten that Ripper didn't write SHIT for Priest. And let's face it, the lyrical content of "Jugulator" and "Demolition" is less-than-stellar. The writing triad of Halford/Tipton/Downing rules the fucking roost, enough said. And even then, look at it this way, Ripper will now be able to do his own thing, his way, without Glenn yanking on his choke-chain.
And BTW, about Sabbath... I wasn't really all that excited about the Ozzy reunion... I always liked their stuff with Ronnie James Dio better. Heaven and Hell is a fucking awesome disc.
