It's very brief, basically, they both end up with broken arms. But apparently in Japanese, it has a double meaning and also means "be friends again". Would be safe to guess the fight might be coming to an end next chapter.
Edit: It does end, conflicting spoilers on whether they both lose an arm or not:
Naruto counters Sasuke's punch,
sending him flying into the wall.
Sasuke's Amaterasu + Chidori vs Naruto's Rasengan.
Big explosion. It's like when they fought here before.
This time both of them fall.
Lying together, they both think of the past.
Sasuke's left hand is broken.
Naruto's right hand is broken.
VS
Using their last drip of power, Kagutsuchi and Rasengan the two collides again.
The valley is destroyed as they both fall face to face.
Naruto explains why he was chaising after Sasuke. When Naruto thinks of Sasuke, his heart hurts a lot.
Sasuke talks too about what he have on his heart. Sasuke too, when he thinks of Naruto his heart aches, and Sasuke thought this would weaken him.
Both of them pass out. When they woke up, a full day already passed.
Sasuke accept his loss and wish to die. Sasuke says that both of them would just have to transplant Sasuke eyes on Kakashi after his death to cancel Mugen Tsukuyomi.
Naruto calls Bullshit on Sasuke dying.
Naruto : Don't make me repeat myself !
Sasuke : ( Starts crying ) Shut ... up, Usuratonkachi !
Both their arms ( the ones they used for the clash. ) are gone and the blood pouring out links both of them.
