Minato's statue in the background
I've read lots of comments about Kishi's hole in the storyline due to the Minato mountain statue in the background.
I don't think it is a hole in the storyline, because if you recall, in the Raikage Vs Minato flashback, Minato said to Raikage "The next time we fight, we will be putting the name of kage on the line"
Therefore I strongly believe that it's isn't some kind of mistake but is intended.
Sorry for not putting in the pic of the manga where Minato says that, but i'm new at this forum posting, so i hope you can all bear over with me :D
