There are also four new armor types to be found. Two of these are two powerful exoskeletons in the game, a heavy reddish-purple one and a lighter black one.

For one, there's an entirely new area you can visit. The space station around Yavin (from the first film) is a new locale that offers a chance to buy most of the new items in the game. But though it makes a nice shopping area, there are some new story elements and combat encounters that will play out here. The space station also gives you the opportunity to meet a new race, the Trandoshans. These lizard dudes are best known through the character of Bossk, the bounty hunter from The Empire Strikes Back.

They've also been unable to say whether or not the content additions to the PC version will ever be made available on Xbox Live.
Ich denke mal, MS wird ordentlich Druck machen, damit der Content auch für die XBox erscheint, dafür hat man ja schließlich den Service (unter anderem) entworfen.
