Damn, if you're gonna retire, then stay fuckin' retired. Just drop a song here and there when necessary, like when people diss you.
If it's true, I would doubt that Dre is producing the majority of it. If it were true, then the album wouldn't be out until 2010, since Dre takes so fuckin' long. I'd rather have The Doctor's Advocate, Detox, and the new Rakim album (hopefully with some Dre beats) come out first.
