Prediction: There won't be a proper Zelda game for Wii U

[Pillow]

doesn't make much sense, they are at least 3 years into development and it's 99.99% sure we will see some gameplay at 2014 E3 (Aonuma even wanted to show it during october 2013).

And the next Nintendo console will take more than 2 years to even be announced, Nintendo doesn't care if the Wii U sells badly, they will find a way to cut the cost of production to make some profit (Gamecube strategy) and continue supporting it themselves.

Also, it is unlikely to sell badly compared to other console Zeldas, they all seem to do the same numbers despite the difference with hardware #s.

If Nintendo wants to sell more Wii Us, Zelda will be one of the last strategy, thing is, the Zelda fanbase is highly loyal, even if they don't like the gamepad or whatever reason you can come up with, they will buy it.
