1)Why are people so upset about Sasuke wanting to be hokage? All of the Uchihas problems were because they had no voice in government. The only one nominated, Madara, didn't make it. Tobirama mistreated the Uchiha and made sure they couldn't act in the government. Sasuke believes that him becoming hokage would make up for past mistakes and that he could prevent anyone dying like Itachi had to die for him.
2)Despite this chapter, I still believe that Naruto and Hinata will be together, unless Hinata dies in this arc. I have no preference, but Sakura talking about the Sannins reminded that Jiraya never got Tsunade. If team 7 takes after their mentors, it makes sense that Naruto won't get Sakura. Also, in the end of things, I can't see Naruto going with someone who has wanted someone else from the very beginning and Hinata, even after professing her love and dying by Pain's hand for Naruto would be turned away. I could see Sasuke going for Sakura most likely but also for Karin. Reason being, if he truly felt bad about his actions during his rebellion, he might feel bad about almost killing Karin. Not likely, but possible.
3)To the people complaining about Minato's power, I don't think it is too far fetched. When he sealed the Kyuubi, he sealed only the chakra inside him, but Kurama's will was sealed in Naruto. That's why he can control the cloak. He isn't that overpowered too, because without Kurama to produce more chakra, Minato only has the store he sealed at the time. Without the temporary use of BM, the only thing he has going for him is his FTG technique.
