EA:

"Our next Star Wars Battlefront will be even bigger, taking players into more locations and allowing them to play with more heroes and characters across multiple Star Wars Eras. There will be new ways to play, including an all-new single-player compaign, and much, much more that we are excited to share with our players in the months ahead."

Finally looks like we will get a single-player campaign, lets hope it will be co-op as well! This info was posted on the EAStarWars Twitter page.
