Free DLC if you register both versions with Club Nintendo, and apparently paid DLC if you only own one version. Will be available starting in Spring 2015.
Other reveals from the Smash Bros Wii U Direct yesterday (sorry for the large pictures):
- Ganondorf, Ness, Jigglypuff, and Bowser Jr. are now default characters
- 8-player matches have been confirmed, with the introduction and return of larger stages to accomodate them
- Jungle Hijinxs stage has a foreground and background plane, which can both be fought on at the same time
- Metal Face and Ridley (too big lol) confirmed as bosses on Gaur Plain and Pyrosphere; both can be KOed, but Ridley can ally with fighters that attack it the most and can be KOed in Time Battles for an extra point
- Classic Mode now based around performing well in a series of matches, and can be done in 2-player co-op
- Event Mode features branching paths which are unlocked by performing objectives
- Smash Tour: Mario Party-like game where you gather characters and increase your stats in preparation for a final Stock Match using your characters as stocks
- Several controller options, including all Brawl options, Wii U Pro Controller, Wii U Gamepad, Classic Controller Pro, and the 3DS
- 3DS can be connected to the Wii U to carry over custom characters and Mii Fighters, equipment included
- Stage Builder now allows you to draw structures using the Gamepad's touchscreen
There was also the premiere of a Bowser Jr. introduction trailer featuring the Koopalings.
