This should've happened ages ago. The K11 got neglected now Kishi used a shortcut to give them their time to shine.
So they all have a random big power-up except for Sai, the elite Root talent, he got shot out of the sky like a rookie.
Sasuke, Naruto and Sakura mirroring the Sannin was hanging in the air since part 1 and now they finally took the last step, still it felt so predictable that they were going to pull this move, look at the last two chapter discussion threads.
I think it is ironic that this chapter is called moving forward since showing all this stuff feels like a step backwards, it's more like a flashback of all the things that should've happened already.
Last thing I didn't get, everybody is taking down lot's of enemies with their new techniques, but Hinata was going for the overkill on a single enemy. 1+2+4+8+16+32+64 = 129 punches, I think you can stop punching now Hinata, you finally mastered the move Neji did in the chuunin tournament
