What if PS4 or 720 have multiple tablet controllers? Is Wii U 'Doomed'?

What do you guys want those consoles to cost? Surface or Vita would cost more or less the same than the WiiU, it seems you guys want that the PS4 and the next XBox cost the same than a NeoGeo, with those 150$ joysticks? Imagine the cost of a PS4 and 4 Vitas...
