Ignoring the fact that it's been announced already, every Nintendo console had a Zelda game of it's own. The series even got it's own Game & Watch and Game Watch game. The WiiU will be no exception. The Virtual Boy is the only exception, it didn't have a Zelda, but they discontinued that after like half-a-year.
Zelda WiiU will arrive no later than holiday 2015. If there's ever going to be a 'TPHD' (yes please ), that game will be on the next console.
