So between Sasuke’s expression and Juugo and Sai’s explanation, I’m pretty sure that this chapter confirmed that Sasuke hasn’t really turned good.
Tsunade definitely still seems to be alive, given from what Katsuyu and Orochimaru said, though she certainly sounds to be on the brink. Whatever it is they’re planning with her, I highly doubt it’s to force her to name Sasuke her successor. First off, I think Tsunade would rather die than name Sasuke her successor, especially when she already seemed resigned to dying before, and she has a whole slew of people she trusts to take over where she left off. Secondly, the Jounins also have to approve before a new Hokage becomes official – it’s not just on the previous Hokage’s say alone. So even if they did manage to somehow force her to name Sasuke her successor, it wouldn’t really be worth much. Sasuke would end up having to take the title by force in the end regardless.
The fact that Karin accompanied that group could suggest that Orochimaru is planning to have Karin heal her, but as another poster previously pointed out, Tsunade screwed him over and caused him an enormous amount of pain before by not healing his arms. What benefit could he possibly get from healing her? It will be really interesting to see what happens with that.
Sakura’s initial tears are definitely related to Naruto and Sasuke, seemingly out of finally seeing them being a team again given the context and preceding panels. Her final expression on the last page seems to suggest that Sakura will be facing down Sasuke once again, and this time, hopefully with Naruto.
And yes, Kishi yes, I want a neo-Sannin battle! It’s funny, the prelude to that battle already sort of happened. That fight began with Tsunade getting Jiraiya out of the way and facing Orochimaru on her own initially. That failed, since he took advantage of her emotional weakness. Recall that at the summit, Sakura likewise tried to ensure that Naruto wouldn’t be involved in her battle against Sasuke. She went to face Sasuke alone initially, and failed because of her emotional weakness. Now Sakura seems to have overcome that emotional weakness, just as Tsunade was able to overcome hers.
I would love to see a Sakura and Naruto versus Sasuke, especially given what Kakashi implied about their teamwork early on in the second bell test. We’ve seen Naruto and Sasuke work together, now I want to see Naruto and Sakura bring down Sasuke together as well!
As for Sakura’s role in this chapter, I wasn’t all that disappointed. Sure, I would have loved for her action to continue, but the soldiers really needed to be healed. It put Sakura’s abilities in the spotlight again in her being able to do something like that so young. It may not have been offensive, but given the fact that she healed pretty much the entire alliance in one move, it’s damn impressive nonetheless. Note also that Naruto wouldn’t be “killing the Juubi and saving the world,” with Sasuke if it weren’t for Sakura healing him – she is an essential component for her healing ability. The fact that she has such impressive offensive feats as well (and they are impressive, considering her one punch killed more Juubi clones than the rookies combined) just makes her that much more amazing.
Plus, I’m pretty certain she’s going to get some more action later on, whether it be against an Edo-Tsunade or against Sasuke himself, so I’m okay with waiting for that, especially since Kishi seems to have really ramped up the speed that events are occurring.
As for the Juubi, no way is it defeated already. We haven’t even gotten to see its final state (which I’m pretty sure we’ll see after all the hype its been given).
