Nintendo not replacing WiiU for at least a few more years! ~Iwata

In reality I think Nintendo will stop supporting the Wii U in a primary way once Zelda U comes out and 2015 wraps up. The system will chug its way to about 15-18 million owners and then just fade away. 

They'll support it through 2015 to keep the few fans that bought the system happy, but Nintendo's not in the habit of sinking tons of money into low-profit ventures either.

Like I said though, even with just the games we know about, through the end of 2015, the Wii U library from Nintendo's side compares very favorably to the entire 5 year run the GameCube had though ... so that should be enough for Nintendo to fulfil their obligation and move on to other greener pastures if they want to. 

I suspect projects that maybe would've rolled onto the Wii U in 2016/17 like a Super Mario Galaxy 3 have already been quietly moved to Nintendo's hybrid platform (though I suppose if its easy to port such a game to the Wii U, then maybe Wii U will get a port) behind the scenes. 

Zelda U comes out in 2016 or 2017.
