Sorry but 2/3 of you're answer is wrong

. Killer Bee or referred to the Eight Tails, he is very familiar with many jutsu's and has very fast speed, he basically gives a head's up to Naruto when he's always about to get hit. Also if he dies, the Juubi would have no purpose to be in the Manga since all 7 Jinchuriikis are there. And, there will be no theory until we get more manga parts on the fight with the Kyuubi vs. Juubi.
Then Kakashi on the other hand will never die, after being in 400-500 episodes of Naruto saying he will be Hokage, I'm sure his hopes are very high to see him become Hokage, also he so far has never encountered a suspicious clue of him getting killed other than the fact of Obito unmasked as Tobi will fight Kakashi, but since Madara came their fight is over, now the Kyuubi vs. Juubi have a fight to settle.
Hinata has a chance of dying after Neji's death, he had a couple of moments to breathe and said " Me and HINATA will risk our lives for you Naruto-kun, no matter what"!
