Sasuke - No way! He won't die until he has fought with Naruto in the epic finale. It's what the series is building up for.
Hinata - No! When she 'died' last time, she made naruto go ape shit. This won't happen again. Series don't repeat specific events.
Sakura - Possibly, but not likely because she seems to have taken a backseat to Hinata as the lead female character.
Kiba/Akamaru - Possibly. Akamaru would have less impact on the manga, but more impact with fans (animal rights etc)
Choji - Most likely TBH. His character was completely expanded on with the butterfly thing and he has achieved enough to die. Characters dont usually die until they have been completely exhausted.
Shikamaru - Possibly, but unlikely due to the fact that his father died. He is now the top strategist in the alliance.
Killer Bee - Only through extraction. It is possible that they can get the Gyuuki out, but not through the same dragon sealing tech as they used before
Gaara - No way. He already died before and we don't know what happened with Madara, but he will probably be saved.
Ino - Not likely, she has too little impact
Sai - Possibly, as he will make a speech about how Naruto taught him to feel emotions, then he might die for his friend.
Lee - I hope not! Kishi already removed his Ninjutsu and use of his limbs. His life is sad already! STOP PICKING ON LEE
Shino - No. As has been said numerous times, he is always forgotten, so it wont have much impact.
Omoi - Too little impact.
Kakashi - Possibly, if he is killed by Obito, but not after an intense battle that reveals a lot about their pasts. I still think that the only person who should be able to kill Obito (through plot) should be Kakashi. The only others could be Minato (due to being the sensei and for revenge for his death and Kushina's), or Naruto, to emphasise the whole 'parallels' thing.
Gai - Only through the 8 gates. This is the only way Gai will die, because we will not be told about an insane life taking technique and not be able to see it before his death!!!
TLDR:
Choji and Kiba are the most likely to be killed by Madara or Obito with jutsu/fighting etc.
Whereas, Killer Bee can only be killed through extraction and Gai through 8 gates.
It is too unlikely that any of the others will die.
