I'm glad to see that Tsunade and the other kages are going to be okay. Hopefully we'll get some nice interaction between Tsunade and Sakura. I was one of those people who wanted Tsunade to die (as weird as it sounds), because I felt that Sakura's character would benefit greatly from it, just like Naruto did with Jiraiya's death. However, this works too. Now Sakura won't have to be sad and I won't have to see one of my favorite characters die. I also liked the parallel between Tsunade/Sakura and Orochimaru/Sasuke. That was a nice touch. :)
I also really liked the banter between Karin and Suigetsu. Karin's comment about how she liked being stabbed by Sasuke was a bit weird, but her "No I didn't" comment seems to suggest that she is still coflicted about her feelings for Sasuke. Then again, she really shouldn't be conflicted. The guy tried to kill her and showed absolutely no remorse in doing so. Then again, he did apologize. I don't really know. I can't really figure out where Kishi wants to go with her character, although I still believe that even if SasuKarin becomes a reality, Karin is going to make Sasuke own up to his mistakes.
As for team 7, the crack are starting to show. Naruto wants to repair the system, while Sasuke just wants to tear it down and then rebuild it in his image. At least, that's how I interpret it. This chapter just shows how broken team 7 truly is. I agree with those was says that Sakura's belief that the old team 7 can be restored (which she got from Naruto) is beginning to fade. She wants to believe that it can happen, but deep down she knows that it's impossible. If Naruto doens't see it now (which he probably won't), I predict that Naruto and Sakura will have to have a serious talk about this.
As for Sai, I'm glad to have him back to once again help Sakura sort out her feelings. At least that's how I hope it will go. She cant keep doing this to herself. That "fake smile" was just heartbreaking. 
It also seems like we will be returning to Kakshi and Obito's fight. At first I didn't even realize that Kakshi had also been wounded. I don't know if Kishi will really kill him. It might happen eventually, but first there are things that need to be sorted out.
