Nope. Wii U is an evolution of Gamecube, the controller is just a better controller for the core audience. Why would you buy a PS4, when you have Wii U with a controller that does all the stuff the PS4 controller and more.

This is pretty much it. When the link cable was released, GBA was supposed to be able to be use as a controller in (selected) games. 

And lose big. There were people on this very site who were saying that the Wii brand would eventually fall. People didnt want to believe

Maybe for the better visuals and all the games you cant play on Wii U? just a thought

I don't think anyone could reasonably have expect Nintendo to go back to Gamecube route, like they did with the Wii U, after the huge success of Wii.

Well, yes. I see you did not read between the lines that the Wii U controller is overshooting the core audience and maybe only the high end user that likes to play with hardware is interested in the controller.

Sure they did. I personally expected them to try to catch lighting in a bottle again and capatalize on another "unique" controller gimmick. Which is what they did only this time people didnt care about the pad like they cared about the Wiimote. What were other people expecting? A Wii 2? That was never gonna happen especially when sales started to dip on the original.

fair enough, but IMHO i think they were tring to get the core gamer and try to get the people who were getting into tablets. As Soundwave said before a lot of the games that were intialied released werent exactly aimed at the core gamer

It was almost the polar opposite of hardware philosophy.

The Wii: intuitive, elegant, and as close to the action on the screen as possible.
The Wii U: complex and convoluted, clunky, and as distracting to the action on the screen as Nintendo has ever been.

The Wii focussed on making complex actions as simple as possible. the Wii U made simple actions more complex. Switching back and forth from Tv to screen was annoying even with the strongest implementations. It was always intrusive to the experience. Wii's Super Mario Galaxy was as immersive an experience as has ever been in the console industry.

On the DS, both screens were always in the field of vision. It's the same mechanic, but the reality of the experience is very very different.

Ninty was both genial and shoertsighted with Wii, it should have launched it with the higher precision and full 3-axes Wiimote Plus, that having actually been launched later enjoyed scarce support as 3rd parties didn't want to lose tens million potential buyers of their games, but had it been standard equipment since the start, it would have brought three benefits, attracting more hardcore games and gamers of a new kind, hardcore motion games with more realistic (and less forgiving) simulation and immersion, delaying the moment existing users got tired of the system and thanks to all this extend the life and increase lifetime sales of Wii. Fully using Wiimote Plus selling potential could have probably given Wii additional sales greater than Wii U lifetime ones, and without the need to develop another interim console. Ninty could have directly developed NX totally skipping Wii U, and what's better, leaving 7th gen still being strong, with a winning image, without the Wii brand name getting tainted and tarnished by falling before its competitors after having so easily overwhelmed them for years.

Nintendo said that the technology for the Wii MotionPlus just wasn't ready in 2006. They should have definitely have launched the Wii U with the Wiimote Plus instead of the gamepad, though. I have no idea why they thought the gamepad would be a hit.
