What I hope to see in BBSv2 is a stronger role for FF characters. That really hasn't been explored, and I'd love to see what happened in that 9-10 years before KH1 to Cloud and Sephiroth (as well as how Zack got killed), Aerith, Yuffie, Cid, and watching Squall going through the fall of Radiant Garden and changing his name to Leon (I suspect that it may have had something to do with Rinoa's absence in the games on top of him being unable to do anything about Radiant Garden's fall, but that's just me. XDDD).
