Young Justice: Legacy has been delayed until November 19. However, owners of the Wii and Nintendo 3DS will now be able to purchase the game as well. This adds to the already announced releases for the Playstation 3, Xbox 360, Wii-U, and Nintendo DS.
For those unfamiliar with the game, it's an action RPG (think Marvel Ultimate Alliance) and has a story that's canonical with the show. The game will bridge the gap of seasons one and two.
