Sasuke is a freaking beast. Damn Sasuke should be able to kill Naruto if he has Sasonoo now, but Kishi will make some BS up and make Naruto fight a weaken Sasuke. Sasuke will be weak from using his eye all this time and Naruto will take advantage of that. Sasuke would destroy Luffy now.
Luffy can make Sasuke faint with his King"s Haki, because Sasuke is a bitch.
