I thought the "Keyblade war" was in BBS...
I think it's one of those wait and see things, though. D;
Why would a war take place in the events of bbs? The game focuses on, like, six characters that have keyblades. You would call that a war? Wars involve armies, and all those abandoned keyblades were already there. Plus, before now the war had been talked about like a legend that happened long ago. Ten years before kh isn't long enough ago for a legend to have taken place.
