Great find dude... And big thanks to WraithX959 for teaching you.
It explains a lot of things to those people who don't pay attention
to the manga. I think only 10% of us pay great attention to it..
I knew most of the things you said, but I could have never proved them
because I didn't know about the typhoon.
If you pay attention, or as Kishi said underneath he underneath, you will
know all of this with out knowing about the Gods and the combination forming typhoon.
I personally have followed the manga with great attention and
my analysis can prove that. I've also reread the manga two times.
The fact that naruto and sasuke remain brothers and friends no meter what
is in deed true. Even tho they don't want to accept that the fact still remains...
But I noticed something...
The connection you mentioned between senju and uchiha...
You can never combine that connection now...
The sanju clan does no longer exist, beside Tsunade we haven't seen
any one else from that clan...
I think the senju is mixed within the other clans..
What does kakashi have to do with the senju..?
Or naruto, or any one else..?
I still don't rule out their existence BUT we haven't seen
any kind of activity that involves them...
Back on Naruto and sauske...
Yes the will never forget each other and I too think the'll
both fight against madara, and that may be the end of the manga,
unles kishi involves someone else...
I think I've said this already...
I have a suggestion for the end.
Why don't you make a summary of all the legends and religions kishi has used..
I had an intention of doing that, but I'm just amazed buy this post,
so if you like you can go ahead and do it...
Edit:I have read some of the replies and would like to answer.
@Hokage, yes i think Minato in deed had already prepared few things, he was constantly learning and studying and inventing stuff... So he must have had the scroll and that jutsu already, well maybe not completed but very close to it.
So he needed time to prepare, just like every ninja, and our very example is Naruto, he always arrives last, with a new jutsy. The same must have happened to Minato.
Or he was waiting for naturo's birth
@pinoxus
Ok let's have a short explanation for you too

First let me begin with the seals..
Minato split the Kyuubi's chakra into
TWO pieces...
Yin and Yang... And he sealed them in 2 different bodies...
Bottom left panel

Minato sealed the
yin chakra in to himself, using the
shiki fuujin(Shiki fuujin=death god sealing jutsu, the one the 3rd used)
So that part of the kyuub is dead, along with Minato...
But he sealed the
yang chakra in naruto, using the 5 part seal...
http://www.onemanga.com/Naruto/370/13/
Now about the key...
The frog which has the key can twist naruto's seal.
Reinforcing it or loosening it...
Jiraiya loosened the seal once but naruto wasn't powerful enough
to control the Kyuubi and the Kyuubi took over him..
4 tails is to much for naruto (Well maybe now he can control it...)
If you twist the seal open, all of the Kyuubis chakra will be available for Naruto,
But if he isn't powerful enough he'll die and the kyuubi will be reformed..
(After the 4 tails appear naruto's body takes shape of a fox and it slowly burns)
And if he can control it he can Turn in to the Fox, with no damage to his body..
Just like the 8-tails...
SO this leaves the question of:
Why did minato want through all that trouble of splitting the chakra into two parts
This is where the theory of this threads connect to this post.
It that very same chapter, if you look underneath the underneaths,
you will see that even Minato knew of Madara's existence...
This is what Jiraiya suspects too.
He leaved the fox to naruto so he can use it in the final battle...
But wait... Madara can control the kyuubi...
Well my friends.. Naruto has got one part of the kyuubi, and let's hope
that is the part which madara cannot control.
If this is the case, the typhoon along side the Kyuubi(which is also a part of a myth)
will definitely beat Madara... A perfect match for his EMS and abilities
Now I have to read about the Kekkei Genkai....
OK... From the beginning I'm very disappointed...
Ok.. Now I'm very very disappointed...
Why did I even read that...

... -_-"
I think he is confused.... ALOT..
I don't rule out some of the things, cuz the have already
been confirmed by the manga, but many are just out of no where...
If you guys want I can give a counter reply to that...
But only if you want, cuz I'm not in the mood of writing it now..
+ Spending my time during the holidays on a thread...
