there's alot of unsolved things yet to be explored or discovered or shown in comic.. for me.. that indeed look like Naruto was somehow related to the sage of 6 path.. firstly I thought that Naruto need to draw upon kyuubi chakra..and now he can turn into sage mode even when moving.. huge jump there
the one thing i wanna see is.. what power did Itachi give Naruto.. remember the scene where Itachi smiled at the forest after meeting Naruto?
