Lil Wayne has set a release date for the fourth installment of his series of albums, Tha Carter. Young Money's President Mack Maine told MTV that Tha Carter IV is due in stores the same day he is released from Rikers Island, where he has been incarcerated since March, for attempted possession of a weapon. "Tha Carter IV plans we had and still have are to put Tha Carter IV out the day he comes out," Mack Maine told MTV News. "He had so many songs for Tha Carter IV, we said let's just put these 10 songs out [on I Am Not a Human Being] and double-back for Tha Carter IV. He has more songs for Tha Carter IV that are still strong." According to Mack Maine, a welcome home concert is also being planned for the day Lil Wayne is released from prison. Despite his incarceration on Rikers Island, Lil Wayne has remained in the spotlight through various releases, in addition to a series of letters penned to fans and media outlets, with his opinions on popular sports issues. This week, Lil Wayne wrote a hand written letter to Sports Illustrated with his prediction that Rafael Nadal will win the US Open. "I'm a huge [Rafael] Nadal fan," Lil Wayne told Sports Illustrated. "I'm definitely rooting for him to get the Grand Slam and win the US Open. Nadal wins it all."Lil Wayne also predicted Kim Clijsters would take the women's title.
