Nintendo kept innovating till 6th gen. And it competitors improved it. But since 7th gen they have stopped innovating.

Nuh uh. Nintendo kept trying new things after that. Motion controls and a tablet controlers are innovative. They may noy have been the first to think of those, but they were the first to succesfully implement and use those features. Sony and MS can't do that. Sony had the eye toy first but that was unsuccesful. 

And the gamepad is innovative too cause neither MS or Sony could make one that was as good as Nintendo's. MS made a smartglass app to make it seem like a tablet type controller but it wasn't any good. And now Sony is selling the Vita as a controller for the PS4.

1. Nintendo copied motion control idea from philips.

2. Touchpad is not a new idea buddy.

2. I know, but as a controller, the touchpad is a new idea. Game consoles have never had anything like it. 

You can definitely describe some of the ideas for the WiiU gamepad (mainly Nintendo Land mini games) as innovative.  It's just not necessarily innovation that people care for, or are willing to pay 300 bucks for.

And this is where I, and think many others as well, get confused.  Is the WiiU innovation simply a flavor ice cream that people don't want, or that they want but don't value at 300 dollars?  I think Nintendo Land (only Nintendo IP that really made good use of it) is a fun experience that most people will enjoy as well as future games like the Toad Treasure Hunter game.  But for 300 dollars, idk.  People are so accustomed to paying 1-5 dollars for an iphone game that Nintendo probably screwed themselves over by trying to make WiiU more like a smart screen but with 50 dollar games.

You guys may be focusing too much on the innovation of the hardware (of course touch screens and gyrosensing isn't new).  It all comes down to software because that's what consumers really consume.  The ideas made in tandem with the hardware is what we can say has been innovative about Nintendo this gen.  Just, is there much of it outside Nintendo Land, and do people like it/want to pay a large amount for it.

in my experience the gamepad has been most helpful in system navigation and app interfaces.  I love using Youtube on WiiU over any other interface because it's the easiest to use on the big screen.  Also the TV controls are an awesome thing that I'm surprised they don't advertise more.

Sony and MS don't only copy Nintendo :/ That's not even a question of debate, it's downright wrong. All three of them come up with new ideas and all three copy the others, like most industries.

Nintendo certainly come up with the most "new" ideas, but they are also the slowest to accept progress. All in all none of the big three have pushed the industry forwards more than the other in the last 10 - 15 years.

This an industry, not a vacuum. The concept of copying is childish.
With regards to competition and creativity, more money, more problems.

The TV controls are somewhat good. Except the browser is horribly slow. The gamepad should cache the program guide so it never has to load. I end up just using the guide on my DVR. My phone is better. Since I can use my DVR app to program it without turning it on. Nintendo needs to get DVR app support. If they want it to be used more. Also, they need to add more buttons to the TV remote. If you have two devices. A TV and DVR. The arrow keys/numpad don't work anymore for the TV. They default to the DVR. That mode needs improvement.

As for the gamepad. I think it's inovative. But has no practical use. I got more negative use out of it. All menu functions forced on it for no reason. Things like the shop and Miiverse show the same. Which is totally dumb. I couldn't play MK8 with it. The size throws me off. So pro controller is my choice. Wii Wheel has a delay I can't stand. And Pikmin 3 gets nerfed because of it. The map is forced on the gamepad only. The only time I use it is with off TV play. Which I don't do much. Because when I want to use a Wii game. I have to "point at the TV screen." Why Nintendo? let me select the button to engage off TV play from the touch screen or normal buttons. These small things make the gamepad not important to me. So it sits on its charge craddle. While I use Wii my remote and pro controller. I personally didn't mind I wasted money on the gamepad. I care about the games, in the end. If I was interested with Xbox One. I would of bought the forced kinnect model at launch. And just never used it. Plus, I jsut pulled the battery out of it. Only Pikmin 3 "requires" the thing to be on.

In my view, the three fill the industry very nicely.

Nintendo innovates and Microsoft sustains the innovations that are popular. Sony likes to be somewhere in the middle as they like experimenting from time to time, just not going as all-in as Nintendo (Eye toy, their touchscreen dualshock, upcoming VR device).

I'm oversimplifying like hell. But just throwing that generalization out there, that's how I see the big 3 right now.
