Who do you think is going to win the great battle? If you haven't read the mangas then just pick who "you" think would win but if you have read the mangas then pick who you think going to win in the mangas.
Itachi,I'm not saying this because he's my fave Character,but because killing Itachi now Would Cut The Story big time,If Sasuke wins Then he Would not have anymore reason to Ignore Naruto & Konoha & I think Itachi gets one or both of Sasuke's eyes & runs away or something but Comon there's so much left in the story. But i hope this Fight ends soon I wanna see more Madara vs Konoha !
Yeah, well, I hope neither Sasuke or Itachi wins because, the story is far from over, and Sasuke has been whining (sorry I don't like Sasuke much don't kill me) about killing his brother from the start. If he kills Itachi I'll be a sad, sad panda :'( and if that happens there's always Madara! mu ha ha ha ha !
