Nintendo's first party games are the only thing worth owning a WiiU for (possibly it will also be the console for traditional JRPGs as well kind of like the Wii ended up being). So I would like to see more Mario, Zelda, DK, Pokemon and at least one console RPG.

My ideal lineup would include:
New WiiU Zelda
New WiiU 3D Mario game
New DKC game
New Metroid game in the old Metroid style
More on that 3DS Zelda that looks like ALttP
More on Pokemon X and Y
X or Xenoblade 2 or whataver it is from Monolith
A 3DS RPG like something in the Golden Sun series or akin to Radiant Historia
