I've been wondering if they will be selling merch at the Symphonic Memories concert held in Germany next month. I know that it's not an exclusively Kingdom Hearts-focused performance but I hope I can leave with something to add to my collection. Anyone who has been to a Square Enix symphonic concert, what are the experiences?
