I hope it's talking, but not repetitive shit. This kind of talking advances the plot. Some fighting will be nice though.
not necessary the fighting but I want to see Minato and Hashirama arriving at the battlefield, to see:
-Naruto and Kakashi's reaction to seeing Edo Minato
-Minato's reaction to seeing Naruto and Kurama, Kakashi grown up, and Obito being "the masked man"
-Madara's reaction to seeing Hashirama
-Hashi's reaction to seeing Madara and realizing how many people he and Obito killed,
