The sources claim development ceased on the title last October when Disney acquired LucasArts.
Allegedly the company’s focus is now on the new film trilogy and the JJ Abrams-directed Star Wars: Episode VII.
LucasArts would only say that the game hadn’t been cancelled.
"LucasArts has been working diligently to take advantage of the tremendous opportunities that the new Star Wars movies present," said a spokesperson.
"Star Wars 1313 continues production."
Star Wars 1313 was originally an open-world RPG in the vein of Knights of the Old Republic, but under former LucasArts president Paul Meegan it was transformed into an Uncharted-style action-adventure game.
The game's story allegedly reveals the identity of Boba Fett and the Bothan spies, and explains why Han Solo was working for Jabba the Hutt.
