I love stuff like this. Its so damn obvious.
There will be a new Mario Kart, 3D Mario, Zelda as 100% guaranteed IPs within the next couple years.
There is also a highly likely possibility of having a Metroid, Donkey Kong, Paper Mario, Mario Party (or wiiu party), Pokemon (not main), etc etc.
That's obvious and that's what any Nintendo IP fan buys the console for. But I do agree with Iwata that they need 3rd parties too and I certainly hope they go after exclusives along with pushing to assist in anyway with putting out quality AAA ports.
