In some pages, kishi gives hints about what is going to happen in the story.
Some examples to reinforce my point:
These pages and what is drawn on them, are shown way before it happens in the manga.
They give hints about what we are going to see.

http://www.narutobase.net/manga/Naruto/024/2 snake sasuke.

and this one is for the lolz .

So, what about:
http://narutoverse.org/Naruto/558/03-04/ titled ''the two fates of destiny''.
We already know sasuke can use hawks.
The diamond on his forehead is similar to the diamond on susanoo.
Will we see some kind of hawk sage?
Will sasuke grow wings?
Sage modes do show features of your animal.
Sasuke is familiar with sage mode, even though it might not have been under the name ''sage mode'' at the time, the curse seal is actually a sage mode.
Juugo is from a clan that can absorb natural energy and they use an ability similar to sage mode, called sage transformation.
Sage_Transformation(from the wiki):
Sage Transformation (仙人化, Senninka) is an ability wielded by Jūgo's clan, which increases their physical abilities and allows their bodies to perform various shape-shifting feats due to their innate ability to passively absorb natural energy. It is a multifaceted ability that permits them to achieve feats ranging from creating various weapon-like appendages to even consuming other human beings, as well as a general increase in their physical capabilities. In the experiments created by Orochimaru, this ability is referred to as "Cursed Seal Transformation" (呪印化, Juinka).
While these clansmen can absorb natural energy passively without being turned into a statue, as those who failed to learn senjutsu do, their bodies cannot control the immense power surges that accompany the transformation and as such, are prone to sporadically going berserk.
I would like to add:
Juugo gave sasuke, some of his flesh and chakra, when sasuke his chest was blown off by killer bee. Telling karin, that he would heal sasuke and that sasuke is already accustomed to his flesh and chakra.
Sasuke has juugo his flesh and chakra.
tbh, i say, that picture (chapter 558-03-04) will give us a look into the future, just as other pics have done.
What do you think?
