I agree with this so much. It is really quite a shame how underappreciated Sora and Riku's KH2 outfits seem to be among the staff. For some reason the dev. team really likes Young Sora and Young Riku. Not saying I don't, I just feel like they used their younger appearances one too many times.
That being said, I am beyond stoked to see what the new duds will be for Sora and the other heroes in Kingdom Hearts III. I hope Lea gets a new outfit, particularly. Not that the black coat isn't cool, it just feels like it'd suit him better if he had the garb of a Keyblade wielder.
