Yeah PE.
That's a very irregular sort of transplant.
Itachi used a Genjutsu on Naruto, it can't be used for a sharingan transplant.
I wouldn't be shocked if he got it somehow, but it'd be utterly stupid of Kishi and friends to have Naruto obtain a Sharingan that way.
Your right about Nagato. Shippuden is the name for the anime, and the anime hasn't shown Nagato being referred to as an Uzumaki. I actually never thought Itachi was a good guy yet he was. I never thought Jiraiya would die yet he did. Many things can happen, but hoping for a Sharingan transplant through Genjutsu is worthy of a :flaw:
