The rumors are true.  Arnold Schwarzenegger will be back for Terminator 5! Justin Lin is set to direct.  The only issue now is what studio will back it and where does the story line go?  Terminator: Salvation did ok at the box office not a great as originally planned and that's because of the storyline around its main character.

Terminator 5 appears to be going back in time just like Skynet with Arnold Schwarzenegger returning as the main draw.  We'll keep you updated.
