i was thinking exactly the same thing, if it has'nt happened in the manga how can they possibly show it in the anime.It looks as though they are mid-fight. I can see why people are pissed off about not seeing the Kakashi rampage and such, but Kishi will touch back on those fights soon. There is no way after all the hype he built up around the 7 ninja swordsman an the kages near Gaara's troops that he won't actually cover the fights. He will get to them, trust me. We won't see 100% of them, but we will see every major casualty, whether they are allied deaths, or more likely, more edo sealings. It was disappointing that we saw so little of Dan and Kakuzu though.....that seemed too rushed to me.
And why are so many people saying that the Gaara/Kage fight and the Kakishi rampage will become filler fodder for the anime? Thats retarded, seriously. The fights will happen in the Manga, maybe not in their entirety, but they will happen. Plus, there has never been a case, in any manga, where such fillers were added that I am aware. Yes, sometimes small additions are made to a battle in order to have the episode end when they want it to, but there is no way the anime would add an entire battle within the main storyline that wasn't shown in the manga, its nonsense.
BTW, great chapter, A and tsunade going to stop Naruto and Bee.
I wonder what happened to Itachi and Nagato's fight.
