Amazon shows that Detox will be released on 2/15/2011. Dre. only stated that he is coming 4/20/2011. CD's music/movies are released on Tuesdays nationally, not on Wednesdays, so I would assume that 4/20/2011 kicks off a tour/marketing schedule.
I now expect to hear news regarding the release of the cognac/sparkling vodka (soon), if this CD release date holds.
