My prediction for the end of the series is:
Naruto will die fighting Sasuke but do something to convince/force him to see
the light
and therefore have won.Sasuke will be shown years later as the next Hokage and a giant statue of Naruto will bridge the dueling statues at the waterfall having reunited the clans.
"And so, Naruto showed us that one man could triumph over adversity. And although Naruto's battle was tragically cut short…"
Sasuke- Zzzz...Change the channel Sakura!
"That's our Hokage!"
