"We've arced out stories for a second picture and indeed a third picture, but I would never be so bold to presume another film. That's in the hands of the fans," said McG in regards to the possibility of additional sequels.
"We're very pleased with the way the picture turned out and the balance between the action and the story and the character and honoring the hard-core 'Terminator' fans but still creating an accessible picture that works for the un-initiated. So you can walk into a cult and understand what's going on," he said.
As for star Christian Bale, who admits to being very particular about his movie roles, he is also tentatively optimistic about the possibility of his return as John Conner.
"I'm very happy with people anticipating that we will be given the opportunity to make a second one," Bale said. "But let's not get ahead of ourselves. I just want to see if this one does well enough.
"Then we get a chance to make a second one. And then it will be about script, you know," Bale told Nancy.
"If fans jump up and down and say, 'Hey, we want another "Terminator," Then we're ready for them and will see," McG concluded.
"Terminator Salvation" opens May 21.
