Seriously, guys... you think Sasuke will die? -_- If he dies, then the whole point of trying to bring Sasuke back (which is like the whole main reason why part 2 existed in the first place) would be considered useless and invalid. Furthermore, Kishimoto knows well NOT to do that or else that would ruin his career of being a manga artist. That's considered bad writing if he just suddenly decides to permanently take him away. One more thing, he's like... the last Uchiha ever to be alive. If Kishimoto decides on making a part 3, keeping him alive would provide more ideas for a new plot. Oh and by the way, Kishimoto loves Sasuke too much. He got no balls to do that.
Sakura, Sai, and Naruto are out of the question. It's already been hinted that they live right after the war so why force the idea of killing them off?
It can't be Kakashi either. He's got this Obito charm going on, and he still has this "role" he has to play in the new generation. That fact in itself is already a reason why he lives after the war.
You know what, I think this rumor about killing a member of Team 7 isn't even real. Either it's a mistranslation on an interviewer's part, or it's just made up by some random dude who wanted to spark a war in the fandom. I say we should just wait and see what happens.
