Based on the direction the manga is going, we can safely assume that the next few months would be comprised of Madara kicking asses. We can also classify the good guys into a few broad categories as follows:
Category A
Characters who are immune to being killed off
Naruto, Sasuke
Category B
Characters who may be called upon to sacrifice own life
Sakura, Gaara, Tsunade, Gai, Kakashi
Category C
People who are totally expendable (i.e. will be killed out of nowhere, e.g. Neji)
Onoki, A, Mei, Choji, Hinata, Kiba, Lee, Shikamaru, TenTen, Ino, Suigetsu, Karin, Jugo, ET Hokages, Orochimaru, Zetsus

My wild predictions:
Gaara learned the life transfer technique from Chiyo's brother after he himself was saved using the same technique performed by Chiyo. He will sacrifice his life to revive Naruto.
Sakura will sacrifice herself to revive Sasuke.
Tsunade will use up all her chakra trying to save everyone else only to find out that Madara can deal out more damage than she can heal. She will die in the middle of a heated war.
Gai will die using his trump card: the 8th Gate.
Kakashi will die trying to protect one of his students, the student he saved may still die though after that, lol.
