Re: Naruto's ending
I'd say the alliance beats Madara, Obito, and the Juubi....maybee Naruto becomes the host of all the tailed beasts...maybee he finds a way to split them all up.
Kabuto, Yamato, and Anko (all screwed over by Orochimaru) will probably end up dealing with him somehow.
Sasuke and Naruto will fight, and that will end up with Naruto returning to Konoha and becoming Hokage. Sasuke will most likely turn from hatred, and maybee become a wanderer like Kenshin Himora. Somehow this challenge between the two arrives after Sasuke arrives in Konoha (possibly with an intent to destroy it...this also fulfils Naruto's promise to bring him back).
Who knows about Suigetsu, Juugo, and Karin...wouldn't surprise me if Orochimaru sacrifices Suigetsu or Juugo for something along the lines of activation whatever the scroll contains.
Sakura probably becomes a medic rivaling Tsunade, Ino-Shika-Cho lead their clans...Shikamaru becomes Naruto's aid. Wouldn't be too surprising if Neji somehow became the Hyuga Clan's leader. Kiba and Shino become prominant figures in their clans. Tenten stays awesome?! Lee is finally a splendid ninja w/ only Taijutsu...probably gets a student that wants to be just like him. Of course it is possible some of these fine K11 members die....only ones I can see dying are Ino, Kiba, Tenten, Neji and Shino (poor Shino/Neji)
Maybee Naruto and Hinata have some sort of realtionship!
