It seems that Ubisoft is not done with Watch Dogs after all. Recently, insider Tom Henderson talked about how the franchise might return.
According to his information, a re-release of Watch Dogs: Legion is being prepared, something like a "director's cut". Allegedly, new content will be added to the game, including a certain "Night Mode". Motion capture sessions are currently being conducted for animations.
It is noteworthy that Watch Dogs: Legion has the worst user rating on Steam in the franchise. It is not yet known when the new edition of the game may be presented.
