The video for Rayman Legends indicates the new title will be a 2D side-scrolling platformer and will add fresh characters, online gameplay, and near-field communication (NFC) support for the Wii U version.
Earlier this year, Nintendo confirmed that the Wii U's tablet controller would support NFC technology. This was most recently used in Activision's Skylanders: Spyro's Adventures. In that game, players use real-world action figures to alter gameplay within the gameworld.
In Rayman Legends, it appears the technology will operate in much the same way. In the video, a user is seen placing a heart-shaped toy on the Wii U's tablet, which then dispenses in-game replenishing health. Also shown in the video is a Raving Rabbids toy, which, when placed on the Wii U tablet, brings the zany hare into the game.
An Assassin's Creed hero Ezio Auditore da Firenze figurine is also highlighted in the video, though the footage cuts to black before any in-game action of the character is shown.
[UPDATE] A Ubisoft representative confirmed with GameSpot that Rayman Legends is in development at Ubisoft Montpellier and is being handled by series creator Michel Ancel.
"This video was intended as a purely internal demonstrative video, and in no way represents the final game, the final console, or their features," reads a line from the statement. "This video was destined for internal production teams who often create game prototypes with work in progress development kits. Ubisoft confirms the development of Rayman Legends handled by Michel Ancel and his team in Montpellier."
A Rayman Origins sequel is not a surprise. Earlier this week, images from a marketing survey provided the first glimpse at a new entry in the franchise. Many of those same images and features are present in the leaked video, including new environments and four-player support.
Rayman Origins shipped last November to a warm critical reception for the Xbox 360, PlayStation 3, and Wii, with subsequent releases for the PlayStation Vita, PC, and Mac.
