Saskue filler, wouldn't be so bad if not for the cheesy sounding translation.
Couple of things I noticed/observed in this chapter:
Kabuto's Sage mode doesn't seem to provide the same physical protection that Naruto's does. If it did, I don't think he would have needed to liquefy his body to protect himself from his jutsu.
Sasuke looks older in those memories than when the Uchiha massacre occurred. Do you think that Itachi implanted that memory in Sasuke? It could have been unlocked with that question. I could see Itachi leaving stuff like that in Sasuke, just as a precaution if circumstances changed and he needed Sasuke's help with something, like facing Tobi to protect the Leaf Village.
Short but nice chapter. It's nice to see Sasuke smile again in a way that isn't diabolical. Also, Kabuto's white noise jutsu reminded me of Naruto's spoiler attack against Kakashi after the time skip. "AAAH! I HAVE TO COVER MY SHARINGAN OR I MIGHT READ HIS LIPS AND SPOIL THE ENDING!!!"
I think people are drawing the wrong conclusion from this battle by suggesting that Sasuke is somehow being redeemed in a way by Itachi by teaming up to fight Kabuto. Sasuke loves his brother, but hates his village for what they did to him. That much hasn't changed.
The only way this can be seen to redeem Sasuke is that it has given Sasuke the opportunity to rebuild an old bond for the first time since he cut them all off.
I get the feeling Kabuto is going to be able to recapture Itachi, forcing Sasuke into a rage at having to fight his brother again.
But again, Kabuto is a great powerful character..he takes on two uchihas, both of them have mangekyo sharingan (sasuke has even ems) both use susanoo which is the most powerful of the sharingan ocular techniques...i mean...WOW
Just release some Amaterasu up in there, its a closed space so there is no getting out for Kabuto.
A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.
Suigetsu's weakness is lightning element. When he was stuck in place by Darui's lightning blade, he couldn't even liquify to escape. Maybe Sasuke will use that against Kabuto.
Also, since Kabuto's speed/reactions might be a factor, this would be a good time for Sasuke to use the Raikage's Lightning Cloak (if Sasuke was able to copy it). I still think that ability would give Sasuke the speed he needs to at least defend himself from Naruto believably, and he hasn't faced a fast opponent since the Raikage.
