Alright... so... containing my fan spirit, I want to give an opinion about this chapter (don't hit me guys... I'm also celebrating, but I want to give an overall opinion about the chapter, and for that, I need to take my glasses off for a moment. XD)
-Well, first of all, I'm not sure if to say that a psychological battle is good or not, but I find this one (Kakashi vs. Obito) to be quite interesting. Illusion vs reality... why do I get the feeling that this will be one of the final statements touched in this battle (maybe something about a reality that Obito can never turn into an illusion or something like that)
-OK, so I need a bit of help. Can someone shed me some light on Madara's words? It may be because I just woke up, but I'm having a hard time figuring out what he means: "It's annoying that I have to take everything apart, just now that I was starting to have some fun."
Also, how did he (Madara) see the bijuus inside Naruto when even Obito couldn't see them (wasn't Obito clueless about that in chapter 573)?
-I have not much to say about Sakura. Her speech had a nice tone to it, it encouraged the alliance and projected Naruto's trust towards everyone. There are some things that only a few people can do, and you do not need a power up for that. To me, this was one of them.
-Shikamaru's intelligence once again comes into play. Its actually quite impressive that he can think straight in a war of this scale (I have a hard time calling shots while in a battle in League of Legends, hahahahahaha). I have to wonder a bit why Madara hasn't targeted him yet?
-Sorry about this Ino, but that expression you have when you say "I just will" reminds me a lot of Inner Sakura. Well, it makes sense that some of our quirks are product of our friends, though XD
Still, once again, very impressive to be able to pull out a global wireless communication. :O
-OK, so this can be a bit repetitive in some mangas, but I actually like how the scenes between the battlefield and the psychological battle switch accordingly to the speeches. This could actually be a good anime episode if done well.
-And finally... Minato saves the day. Well, I have mixed feelings about Naruto expecting him, but there are actually quite a few ways that he could sense Minato, including his emotion sensor "thingy", Kurama's chakra sensor "thingy" (recalling the brothers with his chakra), and well.. it may be a matter of seconds, but the realization of the shape of the kunai is enough to make him realize who just helped. Plus people have already been revived from the dead, so.. yeah.
Overall, I have to say that this is one of the best chapters so far. Just seeing how everyone else has reacted (most, if not all of you, have a positive feedback about it in one way or another) basically confirms this. And well, I wish I could thank Kishi right now. I don't care if we get trolled next chapter (I hope we don't, though), but I think the community needed to see a chapter like this one.

....and... putting my glasses back on... I'll just summarize my feeling on this chapter with a bit of help from one of my favorite actors: Jim Carrey!
