No.

Bad article = bad article.

He gets danger money, one day it will back fire and hurt his pricky face.

Yup, this, Nintendo have a small dedicated userbase of probably under 20 million (at least for consoles) unless Nintendo came up with a console that hit it off like Wii again could they sustain generation after generation with a 20 mill userbase?

WiiU will do more than 20 mill for usre, it still has remenents of the wii, but they can't live off of that forever. Sony have a loyal market in EMEAA and Microsoft have Xbox Live in America, BOTH are stable and I don't care what anyone says it isn't 'all to play for' concerning those two in those regions.

LIVE is hard to chew through, certainly, though an inter-generational fault line is really the only time anyone can even try, but Sony's lead in EMEAA is mostly due to superior supplier relations in that area (where Nintendo especially has always had a diminished presence simply for a lack of having consoles available for sale), one that could be handily broken down were someone willing to try

Mostly, however, Nintendo can prosper so long as they actually remain in the multiplat loop this time (and third parties don't actively conspire to put them out of the loop as they did for no good reason other than spite in the GC days), and otherwise continue to chart the course that they did with the Wii. The masses of samey third party games can provide whatever it is the market's looking for that's distinct from what Nintendo themselves provide

Sony's lead in EMEAA is not 'mostly' down to superior supplier relations. The Sony brand is stronger in these areas and their product is more appealing to audiences there.

And, I disagree with the 2nd paragraph. If Microsoft and Sony come out with superior consoles, why is someone who is not a loyal Nintendo gamer going to buy the WiiU to play 3rd party games on? 

Nintendo can prosper as long as they keep making games the mass market wants...a good start would be not waiting over 15 years to release a new 2D Mario game.

The latter point hinges on multiple factors. While there is certainly a broad audience out there that simply does not see the appeal in Nintendo titles, this audience that is completely non-receptive to all Nintendo titles is a relatively small portion of the market, and while currently people cannot justify buying a Wii just to play that one Nintendo series they like (whatever it may be), they could justify purchasing a Wii U to play that one Nintendo series they like plus all the multiplats

This factors into Nintendo's continued willingness to provide truly compelling software, of course. If they continue to build Wii-style killer-apps, they can force their way into households and then get the core gamers of the household to buy the other games on the device that's already there. If they simply try to cater to the GC audience, the one that Seece outlined, then yes, there will be little reason for it to be anything other than another GameCube, which did support third party parity up until around 2004 (when the third-party conspiracy began)

The inevitable graphical superiority of Sony and Microsoft's successor consoles will have to be weighed against this potential blockbusters on Nintendo's end. Remember that having superior versions of many multiplats in no way helped the XBox, because the PS2's exclusive content was far more compelling.

I proudly agree with the title.

Er, that's a rather arrogant and factually wrong point you have, Xbox 360 and PS3 are video games just as much as Wii games are, nothing Nintendo do is more special, they just chose platformers over FPS, they're still video games.

Nintendo's customers are most likely to abandon them, apart from the fanbase (which is small, wii didn't create a fanbase it created a buzz)

I don't remotely buy the NSMB Wii argument, put that on a Nintendo Gamecube esq title and see how it sells.

Just to pick one one part of the article

"Hard-core gamers want war games, fighting games, sports games etc. and these are genres that Nintendo are not able to deliver on."

Nintendo released (this generation too) the best selling sports game of all time and the best selling (single SKU) fighting game of all time. Before they did the latter, a GC game was the best selling fighting game of all times. If you can break software sales records on the GC, you are doing something right.
