Arnold Schwarzenegger Hasn't Ruled Out Appearance In Terminator 4

Here's the gist: Arnold Schwarzenegger says that if Terminator 4 director McG wishes to bring his big budget sequel to the state of California for a few scenes, he'll reprise his role as the T-800, albeit most likely in cameo form. Also, I'm guessing a big bag of cash, cigars, speedboats et al would play a factor as well. Here's what the governator of Cali told ContactMusic...

"I've never had a dialogue with anyone about it. But if they shoot the movie in California, I would [be a part of it], yes."

Anyone else find it moderately surprising that Warner Bros. or McG hasn't contacted him? With principle photography scheduled to begin on May 5th for the 2009 blockbuster starring Christian Bale, Sam Worthington and the newly cast Moon Bloodgood (I'm skeptical about her for this btw), do you guys and gals think they'll work something out?
