Please only post spoiler pictures, summaries or translations right here for the upcoming Naruto Manga chapter (423). Also include your source where you got it from. Discussions can be done in the Predictions section.
I dunno how closely the English text in the post by thewar reflects the Chinese script, but I thought I'd offer a translation a little bit more in line with the Japanese script here.
Placed my own comments in italics.
First, Chouji's dad remarks how awesome Kakashi is.*
*You'd have to frequent 2 ch to get what the poster is saying.
Kakashi explains Pain's powers and what their battle plan will be.
[Pain's] power would appear to be the manipulation of gravity.*
*any force of attraction and repulsion, really.
Then [Kakashi] asks father and son to help, and they commence their attack.
Explaining the plan's a drag so I won't - suffice it to say father and son manage to restrain Pain.*
*The whole explaining the plan is a drag thing is a remark from the poster.
Kakashi activates Raikiri, but The Ashura Man* stands in front to the cool guy* to blunt the attack with his body.
*Ashura Man: The Path of Ashura
cool guy: The Path of the Heavens (Yahiko)
Everyone: It moved again!? Kakashi: (please make it in time*)
*not sure if his attack's not connected yet, or if he's referring to something else.
There's going to be a fusion (Naruto and Fukasaku?)
Pain: Doesn't seem they/you(?)'re just pretending to be unable to move.
Kakashi: Too late...
Looking around, [Kakashi] sees Chouji and his dad, as well as the other reinforcements, all blown to the ground (looks like the cool guy's doing)
Pain: It's obvious you're no kagebunshin. Consider yourself dead. (Better to err on the side of caution - I'm not about to make the mistake of going in close).
Takes some nails from the ground and points them at Kakashi.
Pain: Know pain!
Kakashi: True, there's no dodging it from this distance...
Naruto Chapter 424
Apparently somebody who works in Jump leaked this on 2chan.
In the mountains, Naruto and Fukasaku are still training, this time they are training on ground but using shunshin and sage mode; the landscape around is completely destroyed and there are huge craters around.
Fukasaku: With the increase your abilities get in Sage Mode, combined with this Taijutsu you've almost mastered, you will be very tough in close combat. However, long range may be a problem.
Naruto: (With my new jutsu, that's not a problem)
Fukasaku: I've got something more to teach you. It will somewhat fix the long range problem, it's a space-time. Hiraishin.
A shot of Kakashi with his Mangekou Sharingan activated, and his forehead above it with a long bloody gash, and the upper part of his ear missing.
Kakashi: Managed to use the Mangekyou Sharingan just in time...
Pain: You are just delaing the inevitable.
Pain raises his hand, and hundreds of small rocks start to float, the rocks take the form of spikes, and they are all shot towards Kakashi. Then a wall of shadow appears between Kakashi and Pain, blocking the spikes; Shikamaru and his father have arrived. Behind them, comes Ino and his father.
Chouji: Shikamaru! Ino!
Shikamaru: I'm going to let Akatsuki kill any more of my friends.
Ino: Chouji! Mr. Akimichi! I'll take care of your wounds!
Pain raises his hand again, and this time a whole house begins to float; Pain throws the house at Kakashi, the Akimichis, and the Naras. However, in mid-air, the house breaks into pieces.
???: Dynamic Entry!
A full-page panel of 6-gated Gai kicking Pain, but pain with his arms crossed blocking the kick while struggling. Last panel a shot of Pain's face, he's angry, and Gai reflected on his rinnegan.
Next Chapter: The Eight Gates.
Spoiler nr 2.
--- Kakashi vs. Pain ---
Pain's nail flies towards Kakashi. He closes his left eye and.. "Mangekyou Sharingan!"
He opens his eye again. The nail hangs just inches from his face. Pain still has his hands stretched out. Debris around them hangs still in the air.
Kakashi gets out of the rubble, but the blocks of concrete he lifted off of himself stay in a floating position for some reason.
"That I had to resort to this.."
He looks around himself. Sees the defeated ninja's around him. He looks at the two Pain bodies still standing. "At least I can take out two of them.."
He fires up Raikiri in both arms.
--- Samui's team ---
They are in front of a closed Konoha gate. Explosions and screams are heard beyond the gate.
Omoi: "Appears Konoha is having some troubles.."
Karui: "Hmm. Well we still have a message for the Hokage."
Omoi jumps up on the wall and stands on top of it.
Karui: "Omoi! What is it?"
Omoi: "It's.. Akatsuki..!"
Karui jumps up on the wall as well and looks around Konoha.
They look at a battlefield with Kakashi still in trouble and Pain still holding the nail.
Omoi: "****! Let's go help him, 't least that'd make a good first impression.."
They jump down and form some seals.
--- Kakashi vs. Pain ---
Deva Pain coughs up blood. "I didn't.. expect you could use.. this kind of jutsu.."
Kakashi stands behind him with both arms inside Deva's body.
Deva Pain: "Your Sharingan's ability.. a time-space jutsu.."
Kakashi: "Not just that. It can see chakra, too."
Kakashi: "I've noticed the other body couldn't dodge earlier because of my rai-kagebunshin."
Kakashi: "It disturbed the chakra recieving metal that you have embedded in yourself."
Kakashi: "So.. now you're disabled.. I can do this."
A kagebunshin of Kakashi appears in front of him and grabs two of the black metal piercings.
Kakashi: "This is the end of this body."
He rips out the chakra receiver in Pain's arms.
Omoi: "I dunno what you did just now.."
Omoi: "But.. damn impressive.. copy ninja Kakashi."
Kakashi turns around.
Omoi holds the nail that Pain fired at Kakashi earlier.
Omoi: "We are here to bring a message to the Hokage."
Karui and Samui appear behind Kakashi.
Samui: "We took care of that one over there. What'cha wanna do with these?"
Samui holds a hand full of black chakra receivers. Behind them is the 3-faced Pain's body.
--- End of chapter ---
Next week: Summit of the Kages.
I personally belive this spoiler is correct...What are your views?
