Will Arnold be back for Terminator: Salvation?

“We can’t talk about Arnold, but perhaps in not talking about Arnold I’ve said it all as far as what our plans are. Let’s just say there may be some surprises...”

Not a straight yes, but as good as. Pending future casting announcements, where director McG (yes, he's *really* called that) can enlighten us further is the film's timeframe: “You know, this is the future the fans had been clamouring for,” he tells Total Film from the set of T4, aka Terminator Salvation (not aka The Future Begins).

“It's not Logan’s Run and spaceships and one-piece jumpsuits and Farrah Fawcett hairdos. It’s a dirty, difficult future.”
