It's not even close to final.
The version you have in your iTunes is from http://www.kanyetothe.com/forum/index.php?topic=3189.0 this snippet that came out 3 weeks ago.
As of October 19th (http://twitter.com/#!/kanyewest/status/27843609415), Kanye was still working on this song, and wasn't close to finished.
This version was going around for 3 weeks, and Kanye clearly stated less than 2 weeks ago he was still working on it, that's not too say it may not be similar, but it's definitely not the mastered, finished version.
