Not sure if this is true or not, but on gamestop website it advertised the free 3ds xl game promotion with the following phrase: "while supplies last" ! Anyway according to Nintendo, this bonus promotion will end on the last day of April. So if what GS stated is true, do you think Nintendo will end the promotion deadline earlier or sooner? Or you don't think they will never run out of the free games since it's not a hard copy rather you download the game you want using a special code?
Well, considering the titles available are digital, "While supplies last" doesn't apply. This disclaimer is most likely just a fail safe for Gamestop, should something impede Nintendo from continuing the free game promo before 4/30.
That being said, I strongly doubt Nintendo would prematurely end this promotion.
