Sorry for the whiplash, but sometimes it'''s best if we just come right out and spill the beans. Yes, yes, we'''re as shocked as you are: 50 Cent, who swore that he would retire from the music biz were he to lose his much-ballyhooed 9/11 record release showdown with Kanye West, has decided '' get this '' to not retire.
Straight from the winner'''s mouth (European sales, people):

''"I don'''t know if it'''s possible for a rapper to retire, rappers are like fighters. They condition themselves to be the best. All rappers think they'''re the best. And they are just waiting for everyone else to recognize they are the best. You'''ll see them come back and back.''"

In other words: JK-Unit. [Gigwise]
