Come someone list to me all these supposed "hardcore" games that Nintendo has released for the Wii U?
Ninja Gaiden 3: Razor's Edge (which is a port of an old PS3/360 game) and ... ? Bayonetta 2 and X are not out yet, there isn't a Metroid game to be seen from anywhere, but we have been given NSMBU, Nintendo Land, Wii Sports Club, Wii Fit U, Wii Party U, Game & Wario, Mario & Sonic Olympics, and Sing Party on the Wii U.
Some mediocre third party support in the way of so-so 360/PS3 ports does not make the Wii U a "hardcore console" anymore than Resident Evil 4 and Red Steel and Monster Hunter 3 on the Wii made that a hardcore console.
Can you show me one single television ad for the Wii U aimed at hardcore gamers? Because I can show you about 6 or 7 aimed at the same family/casual audience of the Wii.
