I hope that the Sai-clone is so real that it fools the Yamato-bunshin, so they allow those 3 getting away.

I mean, I prefer them going back to Konoha and have some character development with the other ex-rookie ni... eight + 3.

And then the rumored (here) civil war lead by Danzou or something.

I mean... we never trully saw Neji, Lee and Tenten's new or improved abilities againt Deidara's clones. And the other ex-rookies only appeared briefly.
