Now that all 3 companies have their consoles on the market I have noticed alot of Sony/Microsoft fans being very vocal about the demise of Nintendo. IMO the Playstation 4 looks like leading the charge in this 8th generation of consoles but the future is hard to predict..... So lets focus on what we know.
In the last generation Nintendo's Wii sold about 20 million more units than the competition and the DS sold over 140 million units and still counting, that equates to significant domiination. In the current generation with a year head start latest figures see them approaching 5 million units with Wii U and over 40 million units with 3DS which is outselling Vita more than 8:1.
Now I agree that the Wii U will probably be surpassed in 2014 by PS4 and even Xbone but Nintendo has sooooo much cash reserves and some incredible IP up their sleeve all this talk of them going the way of Sega and developing for other consoles is frankly a joke. A word of wise to Sony/Microsoft fans, pride is not power. Lets see the results you are predicting come in before you start to celebrate Nintendos demise....
Also, Nintendo have a 5-6 year cycle on their consoles and they are priced for this. Sony/Microsoft have a longer cycle, they release higher spec consoles in the hope they cut the mustard for 6-7 years. So, the fact that Wii U came out a year before the others and with a shorter cycle means it's possible the 9th generation Nintendo console may be out 2-3 years before the competition with much higher spec.
And one more thing, I find it intertesting that while Nintendo does appeal to younger gamers thay have a massive older gamer fanbase. This is proved by the fact that they focus so heavily on retro titles and using old IP for new titles. This would not occur if there wasn't a fanbase of 30+yr old gamers who love Nintendo. Many of the people who frequent this site say Nintendo is too ""kiddie" for them - are they are kids! Take it from me kids, the fascination of explosions and gratuitous violence will dissapate in the coming years and once you get over this games like COD will bore the shit out of you and you will be looking forward to a trip through the mushroom kingdom.
