Is the Wii U gamepad the reason for it's failure? No Mario HD because they are still trying to figure out how to use it?

Last gen almost all big franchises such as Mario and Zelda demostrated why the Wii mote was essencial for the gameplay of their titles. 

For instance, Mario Galaxy implemented the use of the Wii mote briliantly to the game mechanics from collecting coins to swinging Mario. How can nintendo EAD take full advantage of this gamepad? 

However, unlike the Wii where the Wii mote made sense and the 3D on the 3DS adds depth to the gameplay. I don't see the point of the WiI U gamepad, it just seems like an add on peripheral. 

They could have used it to manipulate the level. Implement Pushmo/Pullblox-like puzzles, tap the screen to reshape the level geometry around the point you tapped etc.

MANY possibilities.
