I imagine it's only a couple of years, maybe three, until Idol gets cancelled, regardless of the star power they're pulling in. Unless Mariah & Nicki (lets be honest, like three people from Nashville or something will watch Idol for Keith Urban) prove to be some kind of ratings dream team the show hasn't seen since the heyday of Simon and Drunk Paula, Idol will finally be off the air, something that I think should have happened to years ago tbh. Besides, they can't exactly compare with the likes of Britney Spears & Demi Lovato who currently doing quite well as judges on X Factor. Simon knew when to jump the sinking ship; the rest don't.
