"I know that John Logan and Sam Mendes have come up with a plot for another one, which takes the pressure off because these films take up a lot of time," says a press release by Neal Purvis and Robert Wade.
No one knows yet if Mendes will be back behind the camera to direct Daniel Craig or if he'll only be involved in the scriptwriting.
Skyfall's international earnings total nearly $670M, making it the highest-grossing film (in non-adjusted figures) of the longstanding franchise.
