So apparently cover art for Star Wars: First Assault has been leaked that indicates two things: it will be an XBOX Live Arcade title (at minimum) and is an internally developed game.
People are also speculating, what with the trigger-happy stormtroopers, that this game will be a spiritual successor to Battlefront. They'll find out soon enough, because promotional assets mean this thing can't be very far away; certainly, it would seem to be LEC's next release.
Remember, for all the latest info on Star Wars: First Assault, you'll probably want to hit Google, but if you're patient I'm sure we'll eventually catch up or something I don't know really.
