It probably will happen. Hashi already said Sasuke reminds him of Izuna. And Madara has taken quite a liking to Sasuke too. He's asked him to join him. Before when he "killed" him, he told him it was the end of the road, as if he wanted to leave something for him. And, he even thought to himself how he would have liked it if he had met Sasuke before Obito and was gonna go for Sasuke's left eye. TnJ to Madara with some connection between Sasuke and Izuna is definitely a possibility right now.
