What are the upcoming DLC's for Red Faction: Armageddon?

I would like to know what some of the upcoming DLC's for RFA will be, because I already beat the campaign, got most of the achievements, and I don't really care for the multiplayer mode. I need to decide based on any DLC's that might be good, whether I should just return it to gamestop and get my money back or hold on to it.
