While Nintendo announced plans to implement Mewtwo as special DLC for Super Smash Bros. Wii U/3DS, they recently announced plans to implement other DLC as well, including characters such as Lucas from Mother 3 and Super Smash Bros. Brawl. Lucas and Mewtwo both appeared in previous SSB games; Mewtwo appeared in Melee. In addition, other DLC will include special costumes for the Mii Fighters.
The possibility of future DLC seems promising, with Nintendo also running promotional polls to decide which other characters players would like added to the already large roster of fighters.
With the remake of Xenoblade Chronicles for the 3DS released on the 10th, it serves to revisit the news of the spiritual sequel Xenoblade Chronicles X coming to the Wii U in the near future. The new game will feature elements of the previous title for the Wii: huge areas which reward exploration and item collection richly, large expansive quest lines, and beautiful scenery. The game is the latest in a series of related titles published by Monolith Soft, all sharing the same "Xeno-" name. Be prepared for a long main story and hundreds of side quests to perform as humanity's survivors attempt to eke out a living on a new world.
The second DLC Pack for Mario Kart 8 releases on 4/23/15. If you already purchased the bundle with DLC Pack 1 from last November, you will already be able to download it as soon as it's released. This expansion for MK8 includes new courses and characters, including a track modeled after the F-Zero track Big Blue, as well as Isabelle and the Villager from Animal Crossing: New Leaf.
A strange new game was announced with a trailer, in Japanese. Yuji Naka, famous creator of Sonic the Hedgehog and former head of Sonic Team, leads the creation of this new IP. While not technically stunning (it will also be released for the Wii console apparently), it appears to be a fast-paced flight-based action platformer in which the player controls the main character Rodea with the touch screen of the Wii U or 3DS or Wii remote on the Wii. Also: J-pop.
