Even if it's not resolved I'm pretty sure we'll get some more development for Sisko's story in these. The second one specifically refers to Sisko and the Robinson, so he'll be making some kind of an appearance, and if it's as major a role as it sounds, I find it hard to believe that we won't see some kind of movement in the story started in RBoE.
Well here's hoping. Seeing as that is the Bajoran Worm Hole and DS9 on the Cover. And Sisko is the most important character in relation to that. And certainly Sisko needs to be built back up after hitting good old rock bottom.
