:hey: , i would like to analyse Naruto Manga Chapter 621 & Make a few predictions for 622. So bear with me yeah? 
So in order to give my predictions of what will happen next week for Chapter 622, I'll first analyze the recent chapter and go a little bit more in-depth on its strong association between Naruto's and Sasuke's storyline as well.
So in the beginning of Chapter 621, things are insane at this point, Uchiha Madara and Senju Hashirama are going at it like it's a “Who can summon the biggest entity” contest. Madara was using his Perfect +Susanoo against Hashirama, and with creativity, he literally fused the Susanoo with the Nine-Tailed Beast. And this is all going to be directed towards one person...Hashirama.
Now because Madara is obviously so deep into the darkness, he's basically overpowered just like Hashirama is, but not by too much. Because remember, this battle was before Madara would unlock the +Rinnegan , which definitely would augment his prowess and endurance exponentially. Taking a second glance at this chapter alone, I felt that Madara had complete anger towards Hashirama, but it wasn't so obvious until Hashirama would later mention about their brothers and the village, and I'll mention that soon.
Madara being able to fuse the Nine-Tailed Beast WITH Susanoo just shows how much of a powerful man he is, and I'm sure to even pull this off, you'd have to be so deep in the darkness to unlock the full potential of the Eternal Mangekyou Sharingan. Remember how the Uchiha are considered a cursed race because it's literally in their biology? That the more they love, the more that same love is absent, the withdrawal effects will then to make them more emotional and gain power because of it.
And before this battle, I always presumed Madara had an adequate respect for his brother Izuna, whom he gained the Eternal Mangekyou Sharingan from. That was another dark side of the Uchiha, in order to gain eternal light, they have to take the eyes of someone else of the same power or near it. Hashirama, being the one-man army he is, can easily handle the Susanoo attacks. He's completely diligent and aware in this battle, because think about it!
He's facing a large Nine-Tailed Beast with someone on top of its head controlling its every move! One moment of hesitation, and Hashirama could be crushed! But of course, it's Hashirama we're talking about, and since Senju DNA is about the only thing that has consistent enticing attributes to it, he can just do wood jutsus and other insane summoning.
And it's clear that from this, because we know who Naruto is as a whole, and who Sasuke is as a whole, I can't help but associate Hashirama and Madara with these two! It's inevitable honestly, since Naruto and Sasuke have made such an impact in image and character development (each with their own triumphs and downfalls of course), and even Sasuke was mentioned by the Kyuubi that his eyes has the reminiscent aura of Madara himself.
Even Hashirama acknowledged that if he didn't attempt to give his story to Sasuke, he would surely transcend into becoming the New Madara. Since Naruto Shippuden is a +Shounen genre, you would expect it's targeted towards male audience (which is why Kishimoto doesn't emphasize too much on females other than making Konan and a few others prominent and respectable for their causes).
So while Madara does crazy things like making a Meat Skewer out of the Bijuu Bomb with the Susanoo Sword and flinging it at Hashirama, and then Hashirama deflecting it, things just keep getting more intense. Madara is basically asking Hashirama on what he thinks of his power, kind of like trying to beg for a compliment here. Hashirama just looks at him, and I feel like what was going through his mind was,
“This guy has gone off the deep end.” And then we get Hashirama trying to talk things out, and how that the more they fight, the more they endanger their brothers, families, and the village. The moment he said that, we know Madara's anger augmented tremendously, which means his whole ambition must be more than just trying to be the most powerful shinobi in the world.
Think about it, and it really relates to how Sasuke feels when people talk bad about Itachi, he gets really mad because of the impact and sacrifice he did for the village. And after reading this chapter, I felt Madara truly cared for his brother, because again, the Uchiha clan are more susceptible towards love, and the moment they lose that, they gain power as a withdrawal.
So based from this information, there's many possibilities here:
1. Hashirama is going to mention something that was NEVER distributed before, even to the elites during his time that would contain the darkest secrets. Maybe he did something so full of regrets that made him say in previous chapters to Sasuke that Itachi was a much better shinobi than he is.
2. Because of this, this leads me to believe Hashirama messed up some point, and Madara either took it the wrong way and lived a path of lies that led him to the darkness for more power.
3. Because of the childhood flashback within this flashback, I would presume it SHOULDN'T take the whole chapter next week, just a small portion, because we NEED to see how this battle ended.
4. To have a Thousand Hand Summoning Entity related to Ancient religion towards Shinto gods and such against a Kyuubi beast covered in Susanoo Armor obviously needs some kind of huge ending that will make an impact to us. The beasts were HUGE, so there has to be huge collateral damage.
5. We may be informed on what that form Hashirama utilized, though based from the text, it literally means “Sage Art,” and I know there's debate going on about that, but still, I personally think it's related to Sage Art.
6. The childhood flashback within this flashback might just be a simple thing where Hashirama seemed to dominate during the childhood while Madara was maybe weaker than him.
7. Which leads me to believe that this and other factors that should be revealed next week that Madara is out to get Hashirama for more reasons than to get rid of him to rule the Shinobi World.
