this is my first prediction but what i think will happen through the story is that naruto will taken to the tree so that the tree will leak chakara or some kind of life force into naruto so that he may survive but when they get there nothing happens at first and naruto dies, and saskue dies as well but while they are both dead madara joins the other fight and starts his moon of eye plan. while the whole world is under the genjutsu naruto meets the six path and saskue uses the izangi but since he has ems he doesnt lose his eye sight and naruto come back to life through the tree but since they were dead the time of the jutsu was activated by madara they werent effected by the tech and they fight together to defeat madara and naruto uses THAT jutsu and saskue uses the jutsu given to him by the 1st.
