itachi dies
I'm guessing we go back to gokage vs. madara for a while before Itachi ends the Edo Tensei. It seems like Kabuto is going to break Izanami, however he has had the full blown flashback/backstory treatment which so far is always a death sentence. So the gokage beat on madara for a while, maybe a couple of them get killed, Itachi ends Edo Tensei, Kabuto breaks out of Izanami a moment too late, and is promptly killed by the Uchiha bros.
