According to LatinReview.com Arnold was seen on the set of Terminator Salvation talking to Christian Bale. Our first reaction was that he would have a cameo in the movie, but then realized that Roland Kickinger was playing the role of the younger Arnold. So how will arnold be introduced in to the movie?

Apparently he'll have his face digitally added over top of Rolands and he'll be doing voice overs for the role. That seems to be why he was there that day and would explain the lack of news for his involvement.

Below is the photo and video of Arnold talking with some of the cast and crew. Nice car Arnie, not too shabby at all. Christian Bale, nice truck, though given the success of Batman you'd think he'd drive something a little more flashy.
