I just voted that he died because it would put an interesting twist in midst of this semi-stale plot as of late, but he won't die without taking Kidoumaru with him.

Erm... and I think it was Neji who got hit cause remember he was thinking about what Naruto would do right before he got hit? Neji probably just caught the arrow (in his torso ) in a last ditch attempt to strike back similar to how Naruto caught Kabuto's attack and held him long enough to do the rasengan on him. I'm guessing Neji will either send some attack up the string or pull him Kidoumaru down so he can attack him (possibly some kind of suicidal attack with his byakugan seal like a suicide bomber).
