While Kishi will likely prove me wrong, I don't believe Sasuke will be involved in either of those battles. He has no reason to care about the Kages or Madara. He clearly has a beef with Naruto and he has some "allegiance" to Tobi, but I just can't see him interfering right now.
Kages vs Madara because they are basically hopeless. I'm not sure how Madara would respond to a Uchiha, either. It might have an impact on the story...
I don't know why he would help the Kages but whatever....
he wants to fight naruto he's not on tobi's side because he killed the zetsus and helped stopped the edo tensei. I just hope he doesn't attack naruto when naruto is all beat the **** up

Well Sasuke did once say he was going to kill Madara...sure he thought it was Tobi, but Sasuke is an avenger of his word! Besides, I think Tobi is more important to the story than Madara is thus if Sasuke did help at all it would be in the fight between Madara and the kages. It'd be sort of awkward with him just showing up between the Naruto and Tobi fight; the meeting between Naruto and Sasuke needs to be dragged at more. I think so anyway
Sasuke will go after Tobi now. Itachi said that he helped out in the massacre. His ties with Tobi are most likely broken by now.
He won't help though, MAYBE he'll come in and help the kages...but who knows
