Hello, fellow nin!
Whew. It looks like this forum is turning into a battle royale of words...Lets silence the violence and increase the peace!!! Now onto a few quick hits...
1. I have a feeling Kishi will further develop the gold and silver brother's stories.
a.) They are still part of the "impure world", they just need to be released from the gourd and the pot, respectively.
b.) There's still more to learn about the So6P, his legacy seems to extend into Naruto, Madara, and as Raikage said, maybe the Kin-Gin bros!
c.) Kishi is great at developing characters over a long period of time and then implanting them to be major players in the main story line, i.e. Kabuto! We'll see more of those two knuckle-heads, and that makes me happy.
2. Just a few predictions on what we can expect...
a.) Kishi now has a good chance to switch from Darui's division. We saw him switch to this story line after kakashi defeated the main enemy, Zabuza. Now the main enemy, kin-gin bros have been defeated, so we may see a switch back to Kakashi and his rampage, or kankuro's division and their confrontation with: chiyo, hanzo, kimimaro, and I believe there was one other...
b.) I expect we won't see the edo tensai'd kages in full action until these other fights are finished, since gaara's division is supposed to stall until help arrives. Plus, the kages seem to be Kabuto's strongest summons, besides Itachi and Nagato, whom we probably won't see in action for a looong while.
c.) Curious to see when and where the former jinchuuriki's are used, because each summoned group used against a certain divison has a connection to their leader, or one of the fighters...
Also, Dauri is B.A. He wasn't cocky after winning the fight, even though he could of very well called himself golden because he was a major reason for why the fight against the Kin-Gin bros was won. Instead he gave credit to his whole divison, what a guy. Cloud nins are cool peeps, that's for sure!
See ya later, see ya soon fellow naruto loving nin crew!
