Stop trying to hard at replicating the Wii's success if it happens it happens, by this I mean put out a product that is in the ball park of your competitors , the Wii is dead ,that doesn't mean you need to be better or more expensive just similar hardware , software is the differentiation.
Perception is a hard thing to break and Nintendo's image is what it is and tying to alter it to a more adult orientated image is a catch 22 situation go to far and you risk alienating your existing fans or in regards to minors their parents , don't do anything and you upset people who want more so called adult content and you are labeled the same old conservative Nintendo .
