Maybe they will extract the 9 tails out of Naruto and he WILL die. Following this, Sakura will finally make herself useful and use the same technique as the one used on Garaa and save the day! Then Naruto will be all roooar, Sakura died and save the world from the 10 tails.
Who knows though.
And just fyi, it was noted by Madara(? apparently who that is atm.) that it was surprising she was /still/ alive, as in, unlike Garaa, didn't die instantly. Thus, not saying she wouldn't die, because she obviously does, but that it would take longer for her to be worn out. Likewise, this also bridges the fact that, because she was going to die anyway, she helped Minato with the seal for Naruto.
