^ That would not surprise me. At all.
Anyway, I'm going to take a more optimistic route with 634.
I predict that we will see at least some of the following:
- The reaction to the simultaneous summonings, Sakura's in particular. Naruto, Gamakichi, and/or Minato will say/do something that shoves the manga in the NaruSaku direction, and there will be references to a new generation of Sannin.
- **The identities of Sakura and Sasuke's summons will be revealed as well as brief flashbacks/talk no jutsus as to how they got them. If Sakura's slug is Katsuyu, we will learn the fate of the Kages.** (almost definite)
- Sakura will leave her slug to stay behind and heal people, but she will enter the battlefield and play offense (possibly on top of Gamakichi with Naruto )
- Team 7 will do something cool and deal more damage to the Juubi fodder, the rest of the alliance watching/fighting in admiration
- Inspirational quote by Naruto with Sakura and Sasuke in the background ends the chapter.
