Well its true we ofcourse
don't know whats going to happen but we can speculate. Here's my take on what will and what won't happen.
1. Sasuke will
not surpass Orochimaru (atleast until he opposes Itachi first)
2. Orochimaru won't be killed by Akatsuki and will somehow maintian himself as the main villain.
3. We will see another Naruto vs. Sasuke battle in the future.
4. Sasuke will become a willing apprentice to Orochimaru just has the sound 5 were. But not as loyal in his heart. He will also try to resist the corruption on his body be the curse seal and ask for more conventional strength from Oro.
5. Orochimaru
will take Sasuke's body and become a Sharingan using badass. He will then oppose Itachi at some point.
6. Akatsuki will capture Naruto and begin some freaky ritual to harness the power of Kyuubi
7. We'll see some intense fighting from Kakashi against the likes of Kisame aswell as other jounin fights
8. We'll see the return of the Rookie 9 fighting in some compacity against.... someone
