i wonder that too my friend, i kinda hope he has to fight and defeat his brother. but i really hope he does get the swords, hes one of my fav chars and one of the more underrated ones at that. i really hope to see him realize his dream to reform the seven.Don't we all. It's surprising though since I think that sword would affect Kakashi's speed and his speed is one of his big advantages. Plus how can he do any jutsu except Lightning Blade while holding the beheader. It'll be interesting. I do wonder after the swordsman have been sealed if Suigetsu will finally get to gather those blades.
