one thing that nomura said in one of his interviews is that the theme this time is PROMISE. and i think that promise is the one sora made to kairi at the end of kh ryt? that they would find each other once again. then, another critical fact is what nomura said that the biggest part of the plot is whether sora can find riku and kairi again! so know, it leaves one mystery to me. WHATS GONNA HAPPEN IF THEY MEET AGAIN? its definetely the biggest revelation at the end of the game! what do u think?
