I don't think there will be quite that many options or directions your character can take (you're probably going to be a Sith Apprentice no matter what), but the article I quoted on page one, and which a few people have mentioned since (hinit, hint--read the article!) says that there will be some choices made that impact the game's resolution. There will be multiple endings available, and the decisions you make will determine which ending you get to see. While there will be one "official" ending (the one that will appear in the comic adaptation and novelization) you can also possibly rewrite history and kill Palpatine, etc. if you play the game properly.
