Kanye West appears to be winning his head-to-head battle with 50 Cent for record sales supremacy, but both rappers are likely to move fewer units than they did with their previous albums.

This is the verdict of a Reuters news article that cites Billboard magazine as saying West is projected to sell between 575,000 and 700,000 copies of his new album Graduation, while 50 is likely to sell between 500,000 and 600,000 of his new offering, Curtis.

It won't exactly be a battle of wits, but the rumoured debate between 50 Cent and Kanye West is apparently a go. The two will face off Tuesday on BET to argue the merits of their respective albums - Curtis and Graduation -- according to the Associated Press.
