Nintendo shouldn't go 3rd party and here's why
In this example let's say Mario kart 8 sold 3 million units on the Wii u and made 500,000 people buy Wii u's. After making $180,000,000 off of mk8 and 150,000,000 off of hardware their profits would be 330,000,000. Let's say mk8 was on ps4, xb1 and PC and it moved 5,000,000 units they would come up short with only 300,000,000 in profits. Nintendo wouldn't see their typical profits because the audience for their games is primary on their consoles and without those people buying their systems that's a huge chunk of revenue gone. And the mobile market is out of the question. Mobile games thrive based on cheap entry prices and micro transactions. Nintendo could never get away with charging $20+ for iPhone games so unless all they make is games like Pokemon shuffle that is not a viable market for them

thats what the numbers say, the majority of wiiu owner is male and 20+.

I am one of those majority Wii U owners! xD

But to be honest, Nintendo games may not be kiddie, but majority of them do look kiddie.

Is this based on eShop demographics (i.e. who puts in their credit card for their kid?)  I'm one of those, 35+ whose account is on eShop as well, but the games are mostly played by my kids.

yes? i cant see that. 

and dont come with 3d world, the cat is clearly targeted at the internet and women, not at kids.

Nintendo going third party would be the best thing for gamers, and Nintendo.The expanded audience would favor all involved.

Well it just seemed pretty evident.  Alot of their characters look brightly colourful and cartoony faces so obviously many can mistaken them for kiddish games.  Also their gameplay/controls isn't that difficult either that a kid can easily grasp how to play it.  

Soon, Nintendo will have Splatoon.  The title already sounds kiddish! And whats the concept of that game? To splash others with paint in some sort of childish game of man-hunt or capture the flag. Speaking of which, alot of Nintendo's game titles sounds kiddish too! 

So you can't see how Nintendo games can look kiddie, but you clearly see that Mario 3D world was targeting the internet and women.  Because we all know kids don't like cats too, nor do they like to watch cat videos......sounds like you're just picking and choosing what you want to see. 

The only people saying "Yes, Nintendo should go third party", are dumbass analysts who don't actually understand video games, and MS/Sony fanboys who just want Nintendo franchises on their console of choice.

I would wager that a majority of gamers, even those who are not huge Nintendo fans, but are also not fanboys in the other direction, would agree that Nintendo remaining first party and making their own consoles, is good for the industry.

The more I think about it, the more I really do feel that it would be good if this rumor of a "unified" console/portable platform for their next system would be the best way for them to go. That way all their development efforts would be on one system, and they could put all their resources into making that one console, which takes the WiiU/GamePad idea further, making it a true "play at home or on the go" experience. I think that would work out well for everybody.

Terrible thought. Then they would become a constant rehash company with nothing more to offer. 

And the second bolded is a great thing.

Only true if we do not take into account handhelds... Like at all. With the 3DS, Nintendo consoles as a whole will be right up there with everything else (well actually beating Microsoft fairly easily). This isn't just a Wii U situation.
