I'm not saying that this will be due to any sort of time traveling shenanigans, just your standard New-Game+ or postgame system from other games that let you continue exploring the world or playing the game after you've finished. The Witcher 3 comes to mind, as after the end of that game you're essentially dropped back in to the world just before all of the craziness of the final chapter happens. Same goes for the first two inFamous games, or really most open-world games with a NG+ or postgame feature.
This way, no matter what happens at the conclusion of Stormblood, we won't be locked out of certain areas or be prevented from doing certain quests or tasks based on the events of the story.
