Hiroyuki and Shugo Takahashi recently spoke to Game Informer, where they were questioned about the Status of Golden Sun. Shugo stated One of the reasons that we havent made Golden Sun is because there are so many fans of the game and we dont want to do something half-assed. We want to give it the time it deserves. More Inside Hiroyuki also was questioned on what platform Golden Sun would be on. He stated If I could make something that would combine the handheld and the console with the past and the future if I could combine both of those that would be great. But thats just a thought.
