As others have said, there are multiple factors. I voted "no games", as that's one area that will improve sales once the Mario titles come pouring out, regardless of everything else, but I could just as easily have voted for the gamepad not resonating with casuals and Nintendo's genre variety being too underwhelming for the core.
The Wii U's sales will improve. People are conditioned to playing Mario. For many people, Nintendo's figurehead franchises represent a primary association with video-games. However, I think the Wii was more of an anomaly than the GameCube and the normal baseline for a Nintendo console is going to fall closer to the latter than the former.
