No, it probably isn't Star Wars: Battlefront 3 - and you, Mr Carrying A Candle For Free Radical, need to learn to let go. There's so much else to live for, besides scampering into battle alongside dozens of clone troopers and Jedi. An unannounced shooter, for instance. I don't know much about it yet, but the fact that LucasArts is developing the game alongside Star Wars 1313 suggests that it'll be another next generation console effort.
A system designer's portfolio (cheers Sidequesting) makes mention of a number of core somethings. Here they are: guns, Unreal Engine, Xbox 360 boxart, controllers. If you're wondering whether the game referred to is, in fact, Star Wars 1313, wonder no further - the latter is mentioned further down the page. Ergo, this is a separate project.
