i dont know if you've seen the one art picture that has been released but it seems to me to be the essence of the master sword which if they imply that into this next zelda game i think it would be a great story.

Ive never seen a zelda game that went into the faerie's that much so i don't think it has ever explained where they come from or what their origin is so i would like to see that explained somewhere in a game.

I personally would like to see a game where Link and Ganon are forced to work together to some extent. Maybe an evil force steals both of their triforces and threatens all of hyrule and they both have to stop this force. At the end of this Game Ganon can betray Link and he can stop him once again but I think this could be a cool direction they take the series
