No way the series is going to end after Madara dies. Honestly, this is how I see things going--
*Naruto about to finish Sasuke off, stops* :flaw:
Sasuke: Why did you stop!?
Naruto: Because I love you, braah. :shrug:<3
Sasuke: T^T The truth is, I've always loved you too~
*They kiss and make up*

Madara: Dawg, wtf? :no_ignore:
*Sasuke and Naruto kill Madara togezah, 'cept it's not actually Madara, it's a different dude*
*Kabuchimaru prances off with sixth coffin which contains Madara's REAL body, then sucks up his power and becomes even more of a twisted powerful freak*
Enter-- Kabuchimadara Saga... where Tsunade dies and Naruto becomes Hokage, and finally has the balls to make a move on Hinata.
