A leaked trailer for Rayman Legends on Wii U shows details of the console's functionality

 touch control, graphics and near-field communication capabilities.

The first half of the trailer shows of gameplay footage which indicates that the Wii U is at least up to the graphical standards of PS3 and 360 and demonstrates players using a combination of tablets and Wii remotes to control the game in different ways,using a combination of touch and button control.

The second half of the trailer, though, shows that the Wii U can react to objects places on the tablet screen - rather like how Activision's Skylanders figures interact with the game.

It shows a player placing a plastic heart on the tablet screen, which translates into an in-game power-up, and magicking a Rabbid into the game with another figurine. At the end, most excitingly, it teases an Ezio figurine.
