I'm sure we're going to see something when the war is over.
It's a completely different Arc, so it the "Confining the Jinchuriki" arc when all the war preparation was happening and Naruto was training with Bee. The war itself has also been split into 2 arcs. From the beginning to when the 10 tails was revived it was "The 4th Great Ninja War" and afterwards it was "The Ten Tails" arc.
But even if you were right it would be even MORE to my point. There was little to no time in-between the Pain fight and the war.
