Why are people so obsessed with This Tobi fellow i mean people haven't the faintest idea who he truly is am i right?
I'm obsessed with the Tobi because he knows more about what's going on then any other character in the whole series.
Kabutomaru, as powerful and interesting as he is, is already mostly explained.
Sasuke and Itachi were done being mysterious and interesting around chapter 365. If anything interesting develops out of their interaction, it's going to be Sasuke becoming good... but even that's kinda meh.
Edo Madara vs the Kages is gonna be lame. It's basically going to be Madara torturing the Kages until he gets bored or unsummoned somehow, and even then, he's not going to tell us anything that we didn't already know.
Honestly, everytime i have to watch Kabuto/uchiha or EdoMadara/Kage fights, i'm disappointed. All the good stuff is happening at the Naruto/Tobi fight.
Tobi knows why what's happening is happening... that's something I want to know.
Tobi also happens to be the target of a bunch of side characters that will definitely need saving, but i'm not sure who's going to do the saving (it might give gai a reason to use the 8th gate), or if they all can be saved.
