Ok, so we have Naruto and Sasuke back in action. Guy turning to ashes. The Night Moth was epic! Even more cool to see Guy go through Elemental stages during the Eighth Gate fight. Early on it was red steam, then fire, and finally magma. W know what elemental affinity Guy has now...and it makes sense that he would turn to ashes at the end. I believe that Naruto wants to give him a chance to say goodbye and to know, for certain, that his sacrifice/permanent disability wasn't for naught. That seal he did was pretty snazzy too. Nice reference to the Uzumaki/fuuinjutsu connection. Looks like he instilled a bit of life energy for some reason. We shall see.
The very fact that the sun and moon have been staring us in the face since the beginning is a master trollstroke from Kishi. Then they get up at the same time?! Lol, fusion might have already happened guys! Naruto just shows us how boss he is by kicking the gadoudama away like he's in the schoolyard! ****in right! Even better that Madara doesn't think it's funny now...
Sasuke might get the Rinnegan, but I doubt it. It is more likely he will inherit the Progenitor's eyes. The eyes that gave birth to all others. In my head it looks more like the pattern that the Juubi has. His Susan'oo will be legendary.
Naruto, well...he is now instilled with the life force of 9 beasts, his own prodigious amount of chakra, and in full control of Ashura's abilities. Hopefully he kicks Madara in the mouth for stealing his best friend and nearly killing his brother!

Beast sage mode is now on auto lol. Maybe we will see that final technique of his. That may be the gift Minato will give Naruto. The completion of the rasegan to its final form. It has been stated that Naruto is ready to finish it. Also wanna see his beast shroud now. What frightening combos can Naruto and company hurl at poor Madara now?
I do Think Ashura is where the Uzumaki's and Senju's descend. The sun and the whirlpool denote the Uzumaki's lineage and noteworthy abilities.
The Hyuga's and Uchiha's descend from a common thread as well. I say this because of Kaguya's possession of both at once. Hagoromo's brother is probably the source of this and the spread of Ninjutsu, unless it was Indra's doing.
Wishful Thinking/ Silliness:
When Madara loses, the only honorable thing for him to do would be to use Rinne Tensai to bring back the Uchiha clan. Their destruction was partly his responsibility. Obito must also help rebuild the clan.
They need to drop a memorial right where Guy turns to ash. He did a most noble thing by sacrficing himself to buy time. Doesn't really matter if he dies right here or not. He is never fighting again. His foot crumbled, bones broken and turned to dust. His skin looks like magma armor....awesome way to go out though, lookin' like the molten beast he is! It would be awesome for a tree to sprout when he passes away
One last thing. I can sooo picture Naruto having a good natured rivalry with Sasuke after this is done. Having a race through town, mayhem everywhere. Every tree plant sprouting like crazy as Naruto goes by. And People getting frazzled hair as Sasuke goes by lol. Yeah, I know....silliness. Poor guy just finishing trimming his hedges has to do all of it again! Sakura looking like a ball of cotton Candy >.< okay i'm done.
