Obito have a bunch of sharingans stored in experiment container in Madara's lab.I believe Sasuke will recreate the uchiha clan using his powers and Naruto own as well. People in NB already concluded ,Current Sasuke is yin (creating things out of nothing) and Naruto is yang (giving life to things).Which mean they will work together at some point to revive the Sasuke clan .This will also make peace between Uchiha clan and Senju generation of hatred ,because Sasuke heart desire was to revive the clan so he can see his family again.What do you thing?
