It is coming, if you listen to the track Encore by Eminem featuring Dre and 50 (on Encore, the track maybe called something else).

"Still Aftermath. 2006. Don't worry about that Detox album, its coming! We're gonna make Dre do it!"

Ok I find the track is actually callerd "one last time"

Yeah well I didn't have the album when I wrote that, I only had the mp3 of that song... but yeah its Encore..
