Mutt Williams Says "Indy 5" Isn't Far Away From Filming!

Shia LaBeouf, who played Mutt Williams aka Indy Jr in 2008's "Indiana Jones And The Kingdom Of The Crystal Skull" mentioned, in an interview, that Harrison Ford and himself are set to begin training in the gym for "Indy 5".
This is what LaBeouf said, "I talked to [Harrison Ford]. He said he's staying in the gym, he said he's heard no word, but he does know that [George Lucas] is out there looking for a MacGuffin. He said he's staying in the gym, so it means [the movie is] not so far off. I mean, [George]'s got to let it sit. He's going through his ruminations, which is extensive."
The fifth film was and still is set to be released either next year or 2013, at the latest.
