I think the problem is, that it doesn't have that special game, you know, like Wii Sports. The Wii sold itself with Wii Sports whatever the price was, whatever the controls were, whatever the graphics were.
Look at the Gamecube, it didn't have any game that were revolutionary like the N64 first 3d games and didn't sell good at all. Sure the N64 didn't sell that great either, but you have to take into account the big economic crisis that hit Japan at that time, so marketing budgets were on the low side, plus the fact that the games were more expensive.

All that Nintendo has to do is release a crazy innovative title using the gamepad implementation and market it like crazy: something fun and easy to pickup and play, it must stay simple and straightforward in its core gameplay. At the moment, people don't see the use for the gamepad like the Wii remote was for the original Wii.

(Nintendoland is pretty hard to explain to the average consumer, it could be easily misinterpreted as something you can find on the iOS shop. Not saying it's a bad game.)

Once they manage to make such a game, that is when we will see Wii-level sales.
Until then it will have a hard time to sell greatly. I can only see gamers and a few families buying it, not the market the Wii was able to reach.

Does that bring you happiness?  Am I supposed to be glad about this?  How would you feel if Xbox One wasn't succeeding?

I'm saying what I'm seeing. You sound irrational with that post and completely off base.

oh, well doesn't have to make sense.

Bad, negative press. Similar to the Gamecube which was referred to as a kiddie console with it's lunchbox handle.

there are many reasons, the name, marketing and teh lack of games
maybe valling it super wii u would have been better

Problem being, that the tablet gamepad concept fundamentally isn't useful, if you're glancing down at the tablet controller screen, you can just as easily roll your controller forward or back with Sony's 6axis and have the game pause/switch to overlay mode on TV screen with the same info. Except Wii U is gimping itself because it is wasting it's own CPU/GPU power by displaying that info ALL THE TIME, not just when you want that info.

And then Nintendo is further gimping itself if it wants devs to create fun games, because the console architecture is way more of a headache to program for than either PS4 or Xbone, and even if the devs play along the result will be less than what even a bad effort at those consoles could achieve. Plenty of the 'lite' gaming crowd has moved to Apple or Android devices, and devs find those markets more profitable to make cool funky games for.

If it's not offering a fundentally better experience, then why bother paying the special entrance fee (console) to play Nintendo's games?

Only religious Nintendo fanatics would bother to.  So... maybe they should incorporate as a church for tax benefits?

Where's the all of the above option?

Turned into this

Seriously though in a nutshell I think the Apple/tablet/smartphone revolution forever has changed consumer electronics and it basically stole much/all of Nintendo's blue ocean thunder. Casual/cartoony gaming is still hip ... just on smartphones and tablets, not on consoles anymore.

That combined with horrible management and lazy execution on Nintendo's part.  

The console business has now shifted back towards being driven by 13-35 year old males and Nintendo is feeling the cold shoulder of that audience because they have not catered to that group for the last 6-7 years. 

The casual factor should be in your poll. Casual gamers make up the bulk of Wii sales, and they don't buy consoles every time a new one launches. They will keep their Wii until it breaks, then they will buy a new one.
