I agree with the idea that Kishi should make a new series, but that is only because Naruto is becoming boring and slow. Most likely because of these fillers. I haven't watched Naruto for very long. Anyhow, what you said about Naruto that he will die doesn't imply that Naruto Shippuden or the whole Naruto series will end. He will probably be resurrected back by edo tense or be brought back form the past using a time machine. In short, Naruto won't end with Naruto dead and it would be good if Kishi decided to make another series better than Naruto. He could imply in his new series everything he learned from his mistakes from his current series.
