Bale Being Replaced In Dark Knight Sequel?

If you believe the story on the Herald Sun there are talks for Christian Bale to be replaced in the upcoming Dark Knight sequel by his Terminator co-star Sam Worthington. I am going to say right now that I do not believe for one second that this is true.

Admittedly Sam Worthington is a great actor but why replace Bale? Why add confusion to a great new reboot to the franchise by replacing your star? We end up in the exact same situation when Michael Keaton was replaced as Batman and end up in a big muddy downward spiral. What do you think? Replace Bale? Keep Him? How does it impact the series?
