Ever notoice that some things in that song seem a bit strange, here is the song done backwards, I think you will find this interesting.

My theory for the next game is that there is an opposite of Sora, Riku and Kairi, with a female versions of Sora and Riku and a male version of Kairi who looks realy buff. Look at a video of it and you clearly see to people that look like Sora and Riku but they are girls and all three use keyblades.
