Kotaku’s sources claim that the new 8-button controller has a 6.2 inch screen, two analog sticks, and a camera. The new Wii console (right now known as the Wii 2, Wii HD, or just “Project Cafe”) is said to support the new controller as well as Wii Remote-style controllers for backward compatibility.
So why does the controller need a giant display? Well it would give you some options like putting the player’s inventory or map on the controller screen, allowing players to combine it with the controller’s camera to take photos that could be imported into a game or even turning the controller into a viewfinder. Sounds interesting, that’s for sure. Think of it as the lower screen on a DS, with your TV being the top screen.
