Theory time: I think hiruzen might be the one to die in this arc! The flashback scene he had with orochimaru 2 chapters ago might be in preparation for hiruzens death in the hands of orochimaru! Tsunade will definitely not die because she has to be the next hokage! I honestly can't see anyone in the village who can take her role currently. Shizune is open to death too but still I don't think it will be her since it's too obvious!
