The Wolfman To Be Villain In "Trek" Sequel?

According to various sites on the internet, "Wolfman" star, Benicio Del Toro is rumored to be in talks with "Star Trek" 2009 reboot director, JJ Abrams, over the role of lead villain in "Star Trek 2".
It's rumored that Del Toro may be playing legend villain, Khan, from "Star Trek II: The Wrath Of Khan". This villain is the Trekkies favourite villain, so he could appear. I'd love him to play the new Khan. He's also rumored to be playing a Klingon leader.
