The NES was effectively the Big Bang for Japanese videogame development. Prior to that the Japanese videogame market was pretty much just arcades. There was no Atari 2600 or Intellivision or Colecovision in Japan. So all the best Japanese devs were young, hungry and creative back then. I can see why one would want another crash to clear out the old dinosaurs. But here's the problem: Nintendo is one of the dinosaurs. They're trying to sell the Wii U on a cookie-cutter 2D Mario game and mini-game compilation. While they're making better stuff than contemporaries like Sega and Square Enix, they're not really cutting it. The Japanese gaming industry has just gone so far down the shitter that Nintendo is the best by merely being okay. If there is a crash Nintendo is going down too.
Nintendo's creative output is so generic these days that they're either old men afraid to do anything but the safe bet or they're creatively bankrupt and are relying on shallow controller gimmicks to provide the illusion of a new experience. Nintendo is not young, hungry and creative like the indies. They are old corporate giants and if they survived a crash it would be entirely because of their good financial planning but they wouldn't be leading some new gaming revolution. Don't confuse what Nintendo was (and realistically what Sega, Square, Capcom, Konami, etc. were) for what they currently are. They are not the flagbearers of creativity and innovation in game design. They're a conservative company that makes safe product for the mass market.
