After the DS one I kinda doubt it, at least for a long time.
Hated that they took so long getting that made after the amazing GBA games, but then decided to do the split-story thing again when it wasn't all that likely the game would do well enough to get a sequel and finish the story.
My hope is that someday we'll get a remake of the GBA games (preferably bundled into one BIG game this time), and then if THAT does well enough we can finally get a sequel from there.
Just throwing it out there, but Golden Sun's amazing sprite work would look pretty great in an Octopath Traveler's style engine.
Or just keep it fully sprite based, the GBA games still look so good.
I loved the mix of RPG with powers you can use in the world to solve puzzles, the dungeons, and the collectable aspect of the Djinn.
No RPG has come close to what that series did, and I would love to see more of it.
