Seriously. Outside of Kishi spinning as much yarn as he could of keeping Sasuke away from the village. The amount of vitriol and effort Sasuke put into his final fight with Naruto comes out of nowhere and has no bases. Naruto wins the fight, but the result is the same. Sasuke never goes back to the village, like Naruto had hoped and Kishi had him questing for. Outside of Kishi wanting to hype the eventual conflict between the two, Naruto and Sasuke really had no reason to slug it out.
For perspective: the Naruto vs Sasuke VOTE in Part 1 was 16 chapters. The glorified filler, that was the Kaguya arc, was 11 chapters. The war arc was 225 chapters. Naruto vs Sasuke VOTE 2, was 5 chapters at the tail end of the manga. One chapter for wrap up (699) and the chapter after that was epilogue.
