I agree, to some extent.
Nintendo is indeed too conservative, but it has its pros and cons.
Nintendo KNOWS what makes a game good and they stick to that formula. They innovate in some aspects when it comes to their games, but the "core" mechanics of each game is kept, so that everyone who enjoyed the game before is more or less guaranteed to enjoy it again. I really like that Nintendo does it this way, because there's nothing worse than seeing a beloved IP turn to shit (I'm looking to you, Sega! Ex. Sonic). Some of Nintendo's IPs are what, 20-30 years old and they are still excellent. Familiar characters, sound effects, etc. Nintendo does it very well.
Now, when it comes to hardware, I'm actually glad Nintendo suffers some consequences at times. I mean, if it wasn't for Sony we'd probably be playing super underpowered consoles, with cartridges and terrible networking/online features. Nintendo needs to push their hardware further. Although they did take a big risk with the Wii and it paid off, I still wish it was more powerful...
