Melee had Young Link in it, he could easily have a 'costume change' to fit Celda Link. Unless they make him a character all his own separate from/replacing Young Link.

I was talking to a friend of mine the other day about how I'd like to see a Colour Edit mode in the game. Super Mario Galaxy has (small spoiler) Flying Mario, and it would be awesome if I were able to use the Flying Mario colour scheme in the game. If it wasn't included in the preset costumes, I'd have liked to be able to mix n' match the colours myself. Today's update seems like that won't be happening though, so I really hope they include Flying Mario's colours.
