A few weeks back when Oro returned people were wondering if he'd have used suigetsu to get Jiraiya dna and a lot A LOT of people said what could he possibly add to the fight now.
Well looks like you nay-sayers got your answer. Senjutsu. What can Sasuke do to fight Obito, only ensure Naruto stays alive to hurt him. What could Jiraiya do hurt him. So now who's more useful to this fight Sasuke or Jirayia(not who's stronger but who's more useful don't twist it like you know you'll wanna) If all three of the sannin end up having sage mode(we know Oro does but his old body wouldn't let him use it the body he has now though can't say yet) and Jiraiya gets edo'd game over Obito.
