Yes, the 100 year old Uchiha who has been waging a centuries old blood fued to take over the world to bring his own form of eternal piece will suddenly see the error of his ways by watching one of his enemies die. Kabuto still has plans for killing Sasuke.
I'm sorry if I sound bashy, I was aiming for sarcasm but it seems to me it's going to be Madara arriving at the end of the battle and turns to Kabuto in front of Sasuke.
Madara: I have what I need.
Kabuto: Then we finish our pact.
Injured/Sabotaged Sasuke: Madara!
Madara: I have no further use for you. *disappears*
Kabuto smiles down at Sasuke: Goodbye.
I can see that leading into the darkest hour, but the plot shows to me that this might lead to more than just one battle between Naruto and Sasuke. There is also the possibility that Naruto actually wins and is attacked in the end.
