I know it isn't published by Nintendo, but I would love to see a third entry into the Lostwinds series on WiiU, I loved the first 2 on Wii... make it a little longer and add new abilities and it would be a brilliant gem, if not a killer app. In the more mainstream views, I too would love a Donkey Kong or Metroid game. Even if they simply remade Metroid 2, as it is the only 'unplayable' one, with Super Metroid being still very playable and the original having Zero Mission. even better, release the remake on 3DS and bring out a new trilogy of Primes on WiiU- keep sidescrolling for handhelds and first person for consoles!
I should probably insert some witty or meaningful piece of text here.
