Well, Naruto so far hasn't killed anyone who isn't a clone or already dead. I doubt Sasuke will be the first and only kill he'll have in this whole series.

What I would really like to see (and would also be a good twist) is the 4 previous Hokages just going *sigh*, break free from Edo Tensei and start whooping everyone starting with the ones in front of them. All that from the first page of next chapter.

But no. I bet we are in for Konoha History 101 or something. Hopefully it's interesting.
