Star Wars Battlefront II is a sequel with a lot of potential. The bones of its predecessor were very solid, it was just lacking the content to cover the skeleton. We'll get a chance to see how the next entry is turning out in a few weeks at Star Wars Celebration.
We already know that Battlefront II will have a single player campaign (praise be), so I wouldn't be surprised if that's what they decide to show off at the convention.
The presentation will be at 2:30PM ET/11:30AM PT, and of course, you'll be able to watch it online. You can read the official post from EA here.
