Hines added that he knows "they're working on it" with regard to the PS4 version.
The game's season pass was announced by Bethesda back in September and will included all of the planned downloadable content for the game, beginning early next year.
Additional free update will also be released, and offer both fixes and new features. The game will not have any timed-exclusive DLC.
Fallout 4 launches for PC, PS4, and Xbox One November 10th.
