Via Gamezone.com:

We already know that pre-ordering Star Wars Battlefront will grant you Early Access to the Battle of Jakku, two additional maps set on the all-new planet of Jakku (first shown in the latest Star Wars: The Force Awakens trailer) that let you play out the pivotal moment when the New Republic confronted key Imperial holdouts on the remote desert planet in the Outer Rim. However, if you pre-order you’re also going to get a sweet double-sided poster.

Revealed this week, the poster features a stormtrooper front-and-center on volcanic planet of Sullust, which was briefly mentioned in 1983’s Return of the Jedi, but never actually shown. In Star Wars Battlefront, Sullust will serve as one of the initial map locations, alongside Endor, Hoth, Tatooine and eventually Jakku.

Although GameStop claims it is a double-sided poster, only one of the sides has been revealed. I’m going to assume the other side will be more rebel focused.
