Honestly?
Because of Wii Fit and Wii Sports. The non-gamers who wanted those titles already bought them. A good number of those customers will be content with the Wii and will have no desire to upgrade, while another segment will have moved on from console gaming completely. Such is the difference between traditional gamers and those who bought the Wii because they played it at a party or they wanted to lose 15 pounds. They're not going to spend $300+ dollars for another console they'll rarely use.
Even besides that, you have the confusing identity of the Wii U. They'd have to run some massive advertising to even communicate to many people that the gamepad isn't the only means of control.
