alright, my buddy has been playing this somehow so he's been dropping me clues so i don't know all of it

Alright i think that Vanitas is Ventus' extracted darkness. MX says Ven lost something, right? He even holds out a dark ball.
the timeline i'm guessing will be enchanted dominion, dwarf woodland, castle of dreams, radiant garden, disney town, olympus coliseum, deep space, neverland, and sunset horizons. just a guess
Since Terra has darkness i'm guessing he'll have attacks like RE:COM Riku like dark impulse
I'm guessing MX might try and use Terra to get some power because they seem to have a connection like Aqua and Eraqus so MX could taunt Terra into fighting Eraqus.
Xh could take over people's bodies, yes? I think MX takes over Terra's but i'm not saying he is Xehanort
I believe that instead of ansem reports we get Training reports. After all they're apprentices, right?
I'm guessing that Aqua is sent after Ven and Ven takes after Terra. just saying.
just another thought but Vanitas being Ven's darkness, he could take over Ventus as well and Ven might be the last boss for Aqua's story as Vanitas might be for someone else's
Vanitas is black-haired Sora.
now i'm sorry people but that is what you get for ignorance if you thought i put spoilers for nothing. This buddy of mine has a youtube account and he claims to have found a download for the game so he says he's been playing it. If this is right I'm lucky and i warned you of spoilers
