I'm wondering how everyone thinks KH3's gameplay will be set up. Will it play like Birth by Sleep where you take control of one character at a time and play through each character's individual story before starting the next, will it be more like KHDDD where you are alternating between characters throughout the story, or will it be something we haven't seen yet from the Kingdom Hearts series?
Personally, I think the best option for KH3, in which there might be 7 main protagonists (the Seven Lights), would be a party system like that of most Final Fantasy installations. This sytem will allow for party customization using all characters while perhaps limiting the character that the player can control to Sora or Riku and maybe allowing for control over the other characters at certain times.
Comment with what type of gameplay or party system you think will appear in KH3 or which you think will best fit KH3!
