OMG! Who'll have expect that to happen! Oh no....now there's a high chance that Naruto is gonna get beaten up. With the fully-developed sharingan, Sasuke can now 'predict' Naruto's movement....well, that's unless Naruto is moving faster than Sasuke can react. Strangely, I don't really like the idea of Sasuke having his fully-developed Sharingan now, I don't like it
