I'd like to see some Talk No Jutsu between Madara and Naruto. With this way, maybe we can learn more about Madara himself, like how he died or who -if killed- killed him. Questions are much, answers are scarce, and we need at least three chapter full of talking to have a better grasp on what's going on.
So here's my assumptions.
- Itachi will find Kabuto and will end all of the IWR including himself, but not Madara, since his is a special one.
- Tobi and his gang will face real Naruto and Killer Bee. But their war will be halted a little.
- Õnoki will die. Gaara will be hurt badly enough. Tsunade will succumb to coma again.
- Madara and Naruto will have Talk No Jutsu, either by Kyuubi interference, or some other surprise (Sasuke maybe?)
- Itachi and Sasuke will face again one more time, probably moments before Itachi's last journey to the heaven. Sasuke will continue to be a gay.
- Madara and Tobi will face just after Tsunade battle; and I think Tobi will be the one to finish off Madara.
