Is the Wii U a failure in concept or execution?

IMHO i think the WII U might end up alot like the 3DS in terms of concept. No one really cares too much about the 3d now, after some swore it would make games better. I bet most of the best games on WIi U will barely use the gamepad, just like how some of the best games on WIi used little motion function
