It's probably not true. Naruto was there training for hellas after he died. They would have said something about it to him while he was there or he would have sensed Jiraiya while he was in sage mode. Actually, he definitely would have sensed it in sage mode.
Jiraiya's death had meaning. He shouldn't come back, as much as I like him. People already think deaths are meaningless now. I hope Kishi doesn't ruin Jiraiya's by him being alive the entire time.
"If you will not listen to reason, then listen to my fists!" "You were always a brother... Never an enemy."
If it happens I'll rage quit the series, and stick ot the games.
Why? Well it was the only death besides the 3rd's that actually moved me really, I love Jiraiya, one of my favorite charictars, and that's what made the death have such a big impact on me to have that cheapened would just be a slap to the face.
