Quoted from Cdonnerusmc:
The last few didn't have James Cameron directing either. Not saying it will happen either way. But James Cameron!
He's not directing. He's producing and involved creatively to some degree.
He also was on record as hyping up the last, truly awful Terminator movie as a return to greatness.
Sorry man. This movie is gonna blow.
"Terminator 6 is a currently untitled upcoming 2019 American science fiction action film directed by Tim Miller with a screenplay written by David S. Goyer. The film's story was conceived by Miller, and series co-creator James Cameron, with Cameron also serving as a producer alongside David Ellison, Dana Goldberg and Don Granger."
