Activision has a number of games set for the Wii U, and Skylanders Giants is one of them. Players will be able to use the Wii U GamePad controller to perform actions, like dragging and dropping Skylanders heroes via the touch screen. You'll also be able to use the gyroscopic functionality of the controller to manipulate the game in some form.
The starter pack for the Wii U will run $74.99, includes the Portal of Power adapter, and will come with the Jet-Vac, Cynder, and Tree Rex toys. Expect this pack to be out sometime this Holiday season.
Interesting that the Portal of Power is still needed for the Wii U version, seeing as how the GamePad has the same technology inside it now. Perhaps the next Skylanders game won't need the Portal?
