Okay, okay. I just found this! LOOK!
Its clearly foreshadowing the summoning jutsus from Chapter 633! You can see that naruto has Gamakichi, Sasuke has some snake (it kinda looks like Manda, but its not), and Sakura has a slug- but its not Katsuyu! Its red colored; Katsuyu is White and blue. So for those who thought these were the same summons as the old sannin, its not. These are all new summons! I can't wait for tomorrow!
And you know, its amazing that Kishimoto decided to foreshadow for something so far in the future...kinda amazing.
Okay...I'm reading the new chapter, and that is Katsuyu xD But gamakichi and that other snake are different!
