I don't remember seeing Birth by Sleep - Volume 2, wtf.
SPOILERS
I just watched the ending of Re:Coded. Oh man I am PSYCHED. I was wondering where it was confirmed that the actual person comes back once their Heartless and Nobody are defeated. That also means any of the Organization can come back now. So I'm expecting to at least see Axel in the future.
I also hope we get to play as Ven, Terra, and Aqua again at some point.
