I honestly hope that scientific ninja tools do not come into play here I always thought they were extremely stupid. I do however hope that Naruto gets some form of a tail beast or becomes a human tail beast himself, and that Sasuke somehow gets his rinnegan back or gets an eye that is far more powerful than his original rinnegan but yet does the same thing his original did while still allowing him to access the full range of his Uchiha abilities as well anything less than that will turn the bar to series off for me in a big hurry. Scientific ninja tools never made any sense to me and as far as I'm concerned I have no business being anywhere near the series. Done nothing more than a shortcut.
