OMG it is so funny to see them like this lol. They really beat the crap out of each other. Sasuke confirm that he see team 7 as his family (remember when Kakashi tried to convinced Sasuke to stay when he explain that he lost everything too and that he can deal with the new pain by creating new bond. Sasuke then think of Naruto and Sakura. For him, they were family at one point)
That why in his twisted logic he had to kill them. To become pure evil. Now I'm ready for 699. Imagine Sakura seeing them both like this thinking those idiots. The ways they are she probably can heal them both and they can than break the tsukuyomi. I would rather see the entire next chapter with Team 7 but I suppose that is how it's gonna play.
What sad is tha the aftermath of the fight will be in that last chapter ( Healing them, probably some talk, breaking tsukuyomi, forgive Sasuke for his part ,by forgetting to mention the fight that just happen, then the end. ) I rather have 5 chapter of epilogue than to wait for a movie but it is how it is I guess
