I think the real deal will start after all rookies will get their panel time from 573, Pathway Towards Radiance.
By what I've seen it was Neji/Hinata's now, next will be Kiba/Shino, Lee/Sai, TenTen/Ino,Shikamaru/Chouji and lastly, Sakura by the orders of appearance initially.
In the order of the thoughts we have: Hinata, Kiba, Shino, Chouji, Shikamaru, Ino, TenTen, Sai and Lee or Lee and Sai, whatever, and lastly, Sakura.
The starting and the ending is the same, the pairings kinda match, we'll have to see if it's some sort of action in some sort of pairing like it was 614 with Neji and Hinata, representing the Hyugas, and after, Hinata, alone, as in her speech.
Anyway, the thing is it started with Hinata and will end with Sakura, that's for certain.
And since it started with Hinata on her birthday, my guess is that it will end with Sakura on her birthday (on March 28) and barely afterwards we'll see either the Kages or Sasuke/Oro.
Well, every wish has to be accomplished. Hinata got hers with holding hands, Kiba, with my guess, given he has fought with Naruto before against Madara, aka Tobi, that's what he'll do. Same as Shino. In the Itachi pursue arc. If I remember well, that was actually the set. Hinata, Kiba, Shino, Naruto, Kakashi, Yamato and Sakura.
Afterwards, I'm sure Chouji will be helping him with being "fatass" Chouji as he said, Shika, making his plans as stated. Ino will probably have a big play with keeping the morale and making sure the plan will actually not fail, as she says "I'll have to make sure the foretelling comes true". My guess is that TenTen together with Gai will help protect Naruto as she thought to herself, Lee will probably help him as well with Gai, protect somehow Naruto as Lee thinks and, as Sai thinks, he'll learn once more what it means to have friends and last, but not least, will be Sakura, being together with him, for what, we have to wait and see, as well as them two plus the rest, fighting together, as she thought to herself.
And if my guess is good, since she's the last and had the panel only for herself, it's going to be around 28th of March, her birthday (Kishi, do me a cool gift since mine is on the 29'th

)
