Look at the Rayman situation..A game that was developed especially for Nintendo's new hardware, utilizing all the unique gampad features, and what happens? A complete game is suddenly held back several months so it can ported to Microsoft and Sony platforms thus denying WiiU owners the chance to play the game now.
And this is a 3rd party dev Nintendo is supposed to have a decent relationship with, Nintendo have no hope when it comes to 3rd parties sadly.
