LucasArts parent company has registered trademarks and domain names for something named Star Wars: First Assault.
The filings relate to "interactive entertainment software" for computers and mobile phones, suggesting that yet another Star Wars game is in the works from the studio.
LucasFilms had previously registered website domains for the same name. Given the 'First Assault' name, it sounds very much like this could relate to a new Battlefront game. Although it could just as easily be something entirely new (How about X-Wing please LucasArts, you know you want to).
