Hey
This topic gets discussed in like 3 different topics a month it seems, so lets move it all here and talk about it here
Basically, if you want all the best SWBF3 news, check out http://battlefront3.net/
So far I hope this game has a better focus on Rebels, I'm getting sick of clones atm, I also hope it comes with modding tools :D
Well, I'm guessing they've written a new story for it, although X1, X2 and TFU characters might still make appearances.
Then again, there was an animation reel I saw, fairly recent, with both X1 and X2 in the video. Much more detailed than ES.
