Honestly this doesnt mean anything. At all Japan will always support portables because that is there main platforms. No other place in the world is like that. And besides, we are talking WIi U here not 3ds its always odd that people pull it out to prove something. Now with that being said why hasnt that good 3ds supported translated into at least decent Wii U support? Hell the Japanese studios are actually worse than western ones when it comes ot supporting the Wii U. SE had ONE game Wii U so far. and that was a port game from there western studios Level5 nothing, Atlus nothing, Capcom, two three ports.

Nintendo games sell for only 2 reasons:

1) Nostalgia for the gamers of old days

2) Toddlers (nah just kidding, more like 12 year olds)

3) They have been around for a looooong time, of course their games have altogether racked up a lot of sales in all these decades.

The second is the same reason why COD sells so much. Kids are many, and their parents have to give up to their demands. Adults are more calculative when they are spending money for themselves.

That also means that COD is among the very best games by your logic.

Common sense? According to whom is it common sense and what is it based on? Also, using that common sense, who is the best developer in the world. Their online has been subpar yes, but online is but one element and is not featured in every single game so it would be silly to use that as some kind of deciding factor. Discrediting developers for subpar gameplay, uninspired level design, boring art style, poor visuals or releasing products with significant bugs would be just as valid.

It seems like you're using your own opninion and preferences to define this level that Nintendo needs to surpass. For many Nintendo has already made games that surpass those (or those games never beat Nintendo's offerings to begin with). Now, it's perfectly fine for you to believe that Nintendo is incapable of reaching that "level" but that doesn't mean that everyone has to share that belief. And thus there's nothing silly about regarding Nintendo as the greatest, unless people claim it to be fact or "common sense".

Good for you.

People not buying a WiiU proves me right.

  This is an unsolvable problem for Nintendo, because the only realistic solutions would be to either pay off third parties for ports (thus ruining profitability) or build an audience for such games themselves which would lead into another commonly used excuse ("Only Nintendo games sell on Nintendo systems."), because consumers' expectations for quality and polish would be raised to levels that third parties are unable/unwilling to match.

They are but they still win as the best games. By the way those two reasons you just gave are your opinion  too, there is no careful analysis or data that can back up those two statements.

Super Mario Brothers (NES) isn't sellling anymore. Games sold 30 years ago don't keep on selling up to this day (ar at least they aren't being tracked anymore).

You don't like me using the PS3 version? OK, the 360 version barely sold more than the Wii version, despite being on a system with an existing install base, that was the home of shooters for pretty much two generations (Xbox and 360), and that got the game a week earlier than the Wii/PS3 version.

And the existence of an exception disproves the claim.¹ The claim was that only Nintendo games and cartoony games sell on Nintendo consoles. What CoD3 proves is that other titles can sell perfectly well on Nintendo systems. The sales of future CoD titles on Wii also prove the point, in that, even without advertising, without key features from the other versions, and with a stigma, plus the fact that the most important title in the franchise, which kicked off its huge sales, was two years late on the Wii, the Wii versions still managed a healthy number that invalidated the idea of dropping support for the system.

Oh, and regarding the comparison of "fad" vs "get a second job", here's the thing - first week sales of the game on PS3 in the US? 12.3k. This compares to an install base in that week of 139k. First week sales of the game on Wii in the US? 43.5k, for an install base of 463k. So the game had a tie ratio (not attach rate, that's number of games per console) of 8.85% on PS3, and of 9.4% on Wii.
