Dean, who is also credited for his work in West's 'My Beautiful Dark Twisted Fantasy', said he is yet to start it, reported Ace Showbiz.
"I'm working on the GOOD Music album, of course and 'Watch the Throne 2' - it's not started yet, but it's coming."
The collaborative album has also helped West and Jay Z in getting five nominations for the 2012 BET Awards.
The rap duo have two nods for Video of the Year, and are up for Best Group, Best Collaboration and Coca-Cola Viewer's Choice Award.
