Here's what we know. Naruto when it comes to games is starting to go the DBZ route by telling the same story but using more dynamic ways to experience said story. And also Minato is getting some love by getting an alternate story line for the game's story mode. Which I can hope means we finally get some Kushina love in playable character form. I also have to assume that all those assets from past games won't go to waste as they find new ways to use those characters and add others. So what they do from here is anybody's guess but at a minimum we'll have to wait to get those answers.
