Well, now they have to beat Kaguya, and Sasuke implied only the Rinnegan could destroy the Infinite Tsukuyomi, so the most likely scenario is that he'll develop it in both eyes to combat her, while Naruto unites all nine Biju into a new Ten-Tails like Six Paths told the Biju would happen. But I see no way Naruto could develop the Rinnegan, unless Sasuke pulls an Obito and shoves them into Naruto's head.
