That would be horrible. I won't believe that will happen unless more important characters die without very good reason. Neji is expendable. I am kind of glad that Neji died but it was not a really big build up. He died protecting his sister who was protecting naruto from just a rather basic attack. Sure this is an extreme battle but it's not like this whole scene had a huge build up were naruto was preparing to end the battle and Neji sacrificed himself just so naruto would instantly win etc. As things are now Nejis death has little true meaning. In fact Madara could just start the same attack back up and someone else could end up taking the shot for naruto.
But even after saying all that I am sure that Naruto is going to do something badass now. But I don't think it will end the battle.
It was interesting hearing about edo tensi VS the rinnigan resurrection and how how he can't seal the 10 tailed beast inside himself in his current form. And how obito needs to sacrifice his life. I believe this is likely going to bring Sasuke into the picture eventually. This is kind of the opening that the Sasuke arrival plot needed. Madara is depended on Obito meaning the good guys or someone else have a chance to gain some ground over Madara/obito.
And about another transformation the moment the juubi transformed I knew there would be at least one more transormation. The balbasour thing on the juubis back looks unfinished. Like it will unravel and likely the Juubi will change a lot! I hope the next transformation is the last though.
