the powerful mangeksu sharingan! i suppose Itachi got his when he killed all the clan members, except for Sasuke who was late. would this prove his greatest "capability?" or even surpasses the power of the God of Dark Sun? that black flame thing...
but heck, still have to wait for the next chapter to see Naruto and Sasuke fight - Rasengan vs Chidori!
btw, for the movie goers. i heard that Kakashi's closed friend would be on the upcoming Naruto movie. it will show how Kakashi got his Sharingan and hopefully, he will show off his whole face.
