I don't know if any of you picked up the latest issue of the SW Insider, but they had a pretty good article on this game. Most of it is stuff we've already uncovered, like the AI, the way the environment will react, etc, but they also went into some of the story behind the game like:
You have a pilot ferrying you from mission to mission by the name of Juno Eclipse...she will be a potential love interest for your character ala Jann Ors.
Some of the worlds you will go to will be:
Raxus Prime: a junk-ridden planet that was in the Clone Wars video game.
Felucia: Where you will have to fight Shaak Ti as well as force wielding Rancor Riders
Kashyyyk: Where you will embark on a campaign to enslave the planet
TIE Fighter construction facility: Not really sure what will be going on here.
In addition to Shaak Ti another Jedi you must hunt down is a Jedi Master Koto.
It's an interesting article for anyone who is interested.
