They could do with a new IP that demonstrates the Gamepad functionality in an easy to understand concept. NintendoLand is great but it's not as easy to explain as Wii Sports.
Alternativley they could get in contact with Rovio and get them to make an exclusive Angry Birds game... No seriously take the Ninja Castle game from Nintendoland (So you point the pad at the TV to aim), but instead of using the touchscreen to flick ninja stars you use it to pull back on the slingshot. Then on the tv, you have full 3D corridor like enviroments with the Pigs hidden behind objects and stuff. Therefore you would have a hugely popular IP that's played in a new and easy to advertise way that can only be done on the WiiU.
