An update to EA's Star Wars website from Patrick Söderlund talks about Star Wars Battlefront, saying it is "the biggest launch of a Star Wars video game ever and is the largest digital launch in the history of EA." He also outlines plans for free content coming to the Star Wars action game along with the planned premium season pass DLC:

Best of all, this is just the beginning. We have lots of new content coming over the next several months that will provide new ways to immerse yourself in Star Wars.

In two weeks, The Battle of Jakku launches. Taking place 29 years before the events of Star Wars™: The Force Awakens™, The Battle of Jakku is a free DLC pack* that adds two new maps (including one for popular modes like Walker Assault and Supremacy) and a new mode to the game. The coolest thing is that it’s the only place you’ll be able to experience the pivotal events that help shape the look of one of the next iconic planets in the Star Wars universe. We can’t wait for you to step onto Jakku for the first time with us.

Of course, we are also planning to support Star Wars Battlefront with new content well into the future. We will be adding more of what you love about the game, like new maps and Star Cards, for free in the coming months, in addition to all of the content we have coming with Season Pass. We’ll have more to share soon.
