Considering how most of these things go for new and aspiring writers, Kishi likely signed away the rights to Naruto years ago. So yes, it's likely that a new Mangaka will be found or (god forbid) the Anime will come with new content. Likely indeed. Kishimoto receives a rightful share for every parallel or separately produced product associated with Naruto. He can easily let the remains of his show be milked for several years while leaning back.
