Nintendo of America don't want to localize the RPG games because they sell poorly on Wii.
Mother 3 was never localize, Fire Emblem never localize up until GBA first game of the franchise. That was great and had a success in US then they decide to keep the game localize here. Pokemon will always be localize for the main games. The Fact the those three JRPG aren't even selling anymore now. If they were we would had gotten a release date. Only those who truly knows Nintendo will understand. Call of Duty is more popular than Mario or Pokemon. Here why Black Ops came out before Pokemon BW and BW sold right behind 360 version but surpass PS3 version in 6 month release. New Super Mario Bros Wii and Mario Kart Wii sold a lot more and you say Call of Duty appeals to more people when Wii has more users than 360 and PS3.

It's not my comment that Nintendo is casual- I'm talking about the self-proclaimed  "hardcore" gamers who refuse to buy Nintendo products because they don't want to be associated with the "casual" label - which funnily enough is only thrown around by people similar to them. I'm suggesting that this group of self-proclaimed "hardcore" gamers is growing rapidly through the popularity of games such as CoD. Whereas Nintendo may have easily managed to gain the younger age market before, they may not be able to do so in the future because the popularity of these M rated games is spreading younger.

Still we don't know how the next PS or Box will be, so I can't tell for sure if Nintendo will be on top again or not. IMHO the Wii U will be successful but not as the Wii, same with 3DS which is understandable since DS and Wii are one of the best selling consoles so it's hard to have more success right away. Like someone said in the comments I don't think Nintendo would go third party if Wii U fails and probably they will launch another console in the next next(? generation.
Also, Nintendo always had that fame of being "only for kids", here in Argentina the Wii is SO underrated and the PS3 is freaking overrated, almost everyone thinks the Wii is a $hitty machine only because it's graphics and the games are "only for little children", I was lucky I didn't heard them and bought a Wii because it's such a great console for both kids and young adults like me.
Just my two cents anyway

If there is market loss to other types of machines, it is not unreasonable to think that all types of existing machines will be impacted. If you look at the analysis, the thought is that only Nintendo console and handheld unit players are gaming on iPads and Smartphones. That is simply not true.

Furthermore, the technology mix of the WiiU -- HD graphics and a second screen -- appears to be resonating with many third-parties. If the WiiU becomes a port-box for third parties and still has Nintendo first-party strength, then it could do very well in the next generation.

That's not a good reason, because not every game has to be a hit. Furthermore, those games still help round out the library, which is always a good thing with systems. Look how it helped the DS, and even the PSP.

Nintendo wasnt on top last gen,but still made a profit on the gamecube (not to mention some of their best ever games).Im not too fussed if Nintendo arent on top next gen,as long as the great games are there.PS3 is in last place but still have corking games.

i loved (and still do) the gamecube,it had some really superb games-it was a really underrated console.Zelda the wind waker is a masterpiece.

I was reading this with a british accent. I don't know why, though.

Oh, and hardcore gamers are the hipsters of gaming. 

I'm not completely mad - I don't believe everything that I've written in the OP; however, there are some potential issues facing Nintendo in the future that could at least be similar to that shown in the OP

What worries me about Nintendo is the future, as much as the Wii is being labeled as the kiddy machine, is this true at all? Will these kids have fond memories of the Wii in the future? I'm reall not sure about that. Here in Mexico the most popular system among kids is the Xbox360, even some kids find the Wii boring.... as much as I like the Wii I don't feel it has transmited the same "magic" feeling I felt when playing the Nes. If you think otherwise please tell me because honestly most kids I know prefer to play Xbox or Playstation.
