What if Jiraiya didn't die to Pein?
By this, I'm not saying he would win. But rather successfully flee from the village. I would say he would get pretty beat up, but manages to leave thanks to perhaps a boost in power from sage mode or something like that. Once he would, they would know about the powers of Pein before hand, and Naruto wouldn't be put in a sorrow.

What would happen after this? No idea...
