He didnt die just yet....i see that he will die after either fighting with obito in the other dimension, or after he TNJ's obito he will die from some injury caused by the juubi
Better version? Kakashi's Kamui is except better at EVERYTHING except for turning invinsible.
1. It's faster.
2. It's long ranged.
Sorry, mate. As for the Rinnegan, Kakashi has already been chilled about it when facing Obito's paths, because he's got experience from fighting Pain. The same trick won't work on him twice (and Obito's skills with Rinnegan are MUCH inferior to Nagato's).
And btw, I thought it was obvious Kakashi's sentence to Naruto "I leave this to you" refers to dealing with Madara, Juubi and the mess they have caused while Kakashi is dealing with Obito. Geez, I can't believe some people thought it was a farewell of Kakashi. xD
