I dont know if its new or not but I saw it on the Discovery Channel tonight.
Agent Smith knocks on a door and says "Im looking for Neo, cause he set me free"
What does that mean. Did what Neo did to him in the last movie cause him to realize he could do more than he ever thought possible which makes him stronger? I dont know but it sounds cool!!!
I beleive it was the act of blowing up Smith in the end of M1. If you really want to know, ask in the Spoiler's forum and see if someone that's seen the movie can tell you.
