Those of you who own a copy of Super Smash Bros. for 3DS and pre-ordered the Wii U edition through the eShop can order their soundtrack a little early. Twitter user Crhis Bennion posted an image of the Club Nintendo screen after registering both games with the service (which will have happened automatically for the Wii U version if you pre-ordered it via eShop.) Those who pre-ordered physical copies will have to wait until they have the disk in hand to register it with Club Nintendo. It also appears that Mewtwo’s download code will be automatically emailed to applicable members in spring of next year.
