It's difficult to say. However, given Marin's popularity among fans and the continued references to Link's Awakening in other Zelda games, it is certainly possible that she could make an appearance in a future title. Nintendo has a history of including references and callbacks to previous Zelda games in new titles, often in the form of recurring characters or items. For example, characters like Tingle and Beedle have appeared in multiple games in the series. Given Marin's importance to the story of Link's Awakening and her popularity among fans, it's possible that she could be included in a future Zelda game in some capacity. If Nintendo were to explore a sequel to A Link Between Worlds on the 3DS, this would be a good opportunity to slot her back into the timeline.
