People are allowed to have different opinions. You can't ban people from this thread who want to state them. That's not fair. Personally for me the manga is cover, NH and SS are canon. There's no underneath the underneath. A movie is coming out to explain how NH (and probably SS too) happened. I'd prefer to indulge in fanart/fanfiction. Some of us on tumblr are getting together and we are happy with adopting Shinachiku as our NS child. Fanart/fanfictions over there are great and awesome and fun.
Chatte, if you want to write your theory go ahead... But the chances it's true are almost 0%, despite your claims all your theories have been right in the past for other things. I can't see Kishimoto ending his 15 year manga on a genjutsu. I just can't. We went through that already, and they were ALL released from the IT.
I'm not being a troll, I'm stating my opinion and this is a website for NS fans. I love NS, and prefer we think positively by using our creativity in fanon instead of canon, because the manga is over.
