So would BbSV2 revolve around Aqua in the RoD or would it go farther back in time and you play as young Eraqus and young Xehanort?

that Aqua part is possible, but for young eraqus and xehanort, Nomura once stated that "xehanort-saga" doesnt go any further to past from BBS storyline.

What gave you a hint that it would go back to young Eraqus and Xehanort?

i think its mostly going to be about aqua but i also think you get to play as rikuand mickey during there time in the dark realm even though there time there is short

I believe if it is a game at all, that it will revolve around Aqua. Possibly Riku and Mickey too.

I highly doubt this but, I'm hoping some of the parts from the novel focusing on Vanitas will be in the game as well. If it is a game.

I think it would revolve around Aqua, but would it probably revolve around other stuff as well! I personally don't think any part of it would revolve around a young Eraqus and young Xehanort!

if BBSV2 is real then i hope for aqua and mickey to be playable
