No but really, at least there will be some nice tracks if he's involved. He has been involved with some of her absolute career bests (Govt Hooker, Bloody Mary, TEOG, DWUW...) meanwhile Zedd and Madeon provided totally recycled and/or plain bad productions on ARTPOP.
DJWS is pretty versatile anyways, he could be overseeing production of an acoustic piano ballad album for all we know.
