Scroll Prediction

Based on the conversation of Jiraiya and the Frog,  that  scroll are sealed with key matching Naruto,s Hakke,and that key are left behind by Minato. Jiraiya said Minato intend so that Naruto can complete that special jutsu.And the jutsu might be stronger than Nine tailed Beast.If the person carrying the scroll is Naruto he will use that special jutsu.Or the person that carry that scroll is Uchiha Madara coz he is the only person that can summon Nine Tailed Beast..
