Now that Kabuto is bad-ass we are going to see an even battle between the two. This fight will probably end up showing many weaknesses in the combatants' respective strategies, ultimately, I think that Kabuto will find a way to damage or injure susano'o. We can expect to see Kabuto dominating the fight right away but Itachi will soon give him trouble, then Itachi will allow for Kabuto to release him from Edo Tensai, thus showing Sasuke it's weakness. I would also like to see a way around amarsu.
. Ultimately Sasuke will be faced with a choice, help the shinobi world by giving away the secret to Edo tensai, or be selfish and doom Konoha. what do you think of my prediction?
