Knew it.
Though I never posted a theory about /why/ he looks like Sora, just that I thought he did.
I was going to, and I actually have the theory saved on my computer. It's just that before I knew it, the game was out, and I didn't know if people had found out yet so I decided not to post it (was going to actually, but the forums crashed as I was posting it and I said "screw it.").
No point in posting it now because it'll either be shot down immediately or (if it's right) people will claim I looked at spoilers when I haven't.
Either way, I'd like to find out when I get the game, so please don't tell me.
