Nice attempt, good prediction, however 2 things hard for me to agree:
Minato: "Gedo Mazo? You mean that strange statue?"
Minato is from history even though not as far as from so6p time, still he will know history better and of course he will definitely know what Gedo Mazo is, thats what I feel so he wouldnt ask such things.
Orochimaru: "This Uchiha hatchling... The new path that Sasuke chose... It's something that I think is worthy to protect. That's why I won't let you to harm him anymore, even if I die in the process."
This surprised me a bit, from what I know Orochimaro is always waiting for an opportunity for his own benefits, he would never ever sacrifice himslelf for 'silly' things such as emotions
but he might still help sasuke so that sasuke would help defeat Madara as he would definitely not prefer Madara taking over the world which will be a loss for him(orochimaro) too.
Orochimaru: "You know, I was once a selfish snake, just like you. But now I know something very important... That's why I won't let you do as you please, let's finish this!"
Above statement was Hilarious:leaf:, but Orochimaro can never utter xD
But very good predictions i liked keep up the good work.
