Nintendo could stand for some new, read:modern , lifeblood in their decision making process. All the executives or people in a position to say anything in the company are pushing 60+.
At the end of the day, MS, Sony and Nintendo are console makers whose biggest differentiator is first party games. Each company can make a game machine as weak or powerful as they want. And nothing makes every third party dev happier than having another platform to sell products.
And talk about corporate coffers, Nintendo has something like a $10 billion warchest. MS might be richer, but they are also a company of many divisions and have a high standard of profitability. MS' CEO isn't going to greenlight spending $20 billion just for the heck of it even if they can afford it. Sony is in the worst financial situation.
Yet, Nintendo acts like the weakest and poorest competitor. Once the market dominating game company to now third string. Like any company I've worked at, if you are the big fish, act it. What's the point of being a huge company with a history of success if you are purposely playing for last place (out of 3). The industry makes profits. The money is out there.
All Nintendo has to do to get the user base up and get more third party devs is actually simple. Make a more powerful system which attracts many devs, and have their first party studios make some more games aside from the handful of Mario and Zelda games. Keep making those, but make some cooler and more realistic games that will attract a more diverse gamer set. And then all the Skyrim's, R* games, EA Sports and such will come.
The reason Ninty gets crap ports, kiddie ports (remember all those gimped EA Sports games like Madden with cartoony 5-on-5 gameplay) and doesn't get those long lasting gamers (onliners or microtrans spenders) is because their games have been relegated to more kiddie and niche. If this was the NES and SNES days, they had it all.... but with good fortune from huge third party dev support. As soon as that dries up, their first party games aren't as special or sell consoles like people think.
If Mario and Zelda are such system sellers, N64, GC and Wii U would dominate. They didn't. Each of them actually got crushed, since their third party support was lousy. Wii struck gold with a $250 system that caught fire with motion controls.... a fad that died fast.
