In an interview with engadget, Nintendo’s Eiji Aonuma, director of the Zelda series, stated that he thinks Nintendo takes too long making games and that they are too careful when analyzing different parts of the game. The full quote:


"The way we make games is we’re very careful. We’re very thorough. We’re very detailed. We take a long time analyzing the different parts of a game… almost to our detriment. Almost too careful. I think the need is there for us to make decisions more quickly, weigh the risks [and] see what the payoff is."

I say they should take all the time they need, it's better to deliver a quality product, than to release a bunch of sub-par games. What Nintendo really needs to do though is hire more developers.
