It's Rogue One. The tweet itself reads (used to read) " Rogue One enters STAR WARS: Destiny with SPIRIT OF REBELLION BOOSTER PACKS! " followed by a few hashtags and a link to an article that doesn't exist yet.
So series two is called 'Spirit of Rebellion' and seems to focus heavily on the new movie. I'm not that surprised - when you answer to a franchise, you gotta play the tie-in game. Still, I hope we'll see a sprinkling of other characters for good measure. Thoughts? Expectations? ... Lamentations?
