The reason I'm predicting this is because the Wii U stumbled so catastrophically out of the gate, when Nintendo expected it do well off the Wii branding.
Pokémon is, in a sense, their last true killer app. And I think they know it.
A Pokémon game on the scale of Skyrim or Dragon Age would sell a console like nothing else. They know it does too, they can see it in their 3DS sales when a Pokémon launches.
