There isn't anything wrong with trying new things or even "new gimmicks". There's nothing good or bad about it, it's ultimately up to the consumer as to whether or not they want to accept something, a company can make all the gimmicks they want it doesn't mean the consumer has to buy it.
However, I would say the companies that base their business around gimmicks are prone to high highs and extreme lows.
We're seeing that with Nintendo now.
Live by the sword, die by the sword.
Gimmicks are not really a sustainable form of business because eventually the novelty wears off, unless you can keep coming up with new gimmicks to replace the ones that are fading out.
Which is hard, it's like asking Psy to come up with a new Gangam Style hit every year ... that was a one time phenomenon that took off on the internet and it was a catchy tune, but likely he'll never be able to replicate that.
