The Zelda Wii U tech demo was one of the first things Nintendo showed off when they unveiled the console back in 2011 but we have heard nothing about a 3D Mario Wii U game. Now Satoru Iwata has said launch schedules for a 3D Mario Wii U game and Zelda Wii U will be announced in the future.
But an HD zelda is very high on my most wanred list, as long as it has the tech demo's art style
PS3 constantly comes out with new IPs which is awesome, but Nintendo can sell consoles just on those 3 games alone. There's no significant need to focus on new IPs.
This gen is in its last years, yet they are still churning out new IPs like PS Allstars, Last of Us and Beyond Two Souls
