Pain said that each of the Sannins have their own "unique ability"
Now, this chapter introduces the hermit mode as Jiraiya's
But what is Orochimaru's? The ability to prolong life? To summon the dead?
Tsunade's? Her chakra-saving forehead ability?

I hope we get to see something more cool than just detection and snake attack from the hermit mode.....it just feels like 2 talented frogs glued to Jiraiya's shoulders so far..
