Their hand helds have a much longer lifespan.
Their consoles, though, have been lately mainly sort of "current generation" specs or build slightly upon their previous one (like Wii still have GC compatibility and Wii U has Wii compatibility), and a lower price so they won't have the lifespan of Sony of MS Consoles.
The article talked about the NX building on the Wii U platform but with the next innovation.
My take:
1. Wii U (games that work without the touchpad) and Wii backwards compatibility. Compatible with Wii and Wii U Pro and GameCube Controller Adapter.
2. Games can be 3D compatible (yes, that maybe their next "innovation"). 2D on standard screens.
3. Will have some sort of "XBox One Kinect" device with it. I think if anyone can pull it off, Nintendo can.
4. Can use Tablets, Smartphone, 2DS/3DS as extra controllers and screens.
5. Price for Console with 32Gigs, Pro Controller, HDMI Cable, "Kinect" Camera, and Game Download (Mario 3D World NX in 3D?

): $249.
I think the NX will be the "one to get" and have the immense popularity of the Gamecube and Wii.
