Comic-Con: Arnie Confirms "Triplets"

While at Comic-Con, BIG Arnie confirmed during "The Expendables 2" panel that a sequel to 80's classic "Twins" is in development and is under the working title of "Triplets".
The only thing is that there's no script yet and still no confirmation if Danny DeVito and Eddie Murphy are still joining the Terminator in the long-awaited sequel, even though DeVito confirmed that the film was in development all those months ago.
