The Detroit Tigers are facing a deficit in the World Series, but there is some good news out of the 313, as Eminem has released a limited edition baseball cap which confirms his next album will come out in 2013. 

Mirroring teams that post their championship years on the side of their hat, the D cap has years printed on the side which indicates the 7 years when Slim Shady released a solo album, and the 8th year is 2013. 

Em had said previously that he was just wrapping up work on the Slaughterhouse album before diving into his own album.
