I mean, he "killed Itachi" and his last goal was to revive his clan. Naruto and Sakura accomplished their goals. Why Kishimoto dropped this? Why Sasuke would suddenly get over on something that impacted not only his and Itachi's life but the entire shinobi system? Why would he let Sasuke have an Uchiha with glasses for heiress and that will most probably being a puppet to the Uzumaki and Konoha (if she isn't already)? Will the Uchiha clan become a relic of the past?
