I think one of the things about the industry which Nintendo may have missed before - and hopefully they're addressing now - is that *third parties are consumers too*. Not the same sort of consumers, but you are offering them a product (license to make games on the system) which you want them to have a use for (Use that license to make a game which makes a profit).
Third parties were not convinced by the product Nintendo offered with the Wii - incorrectly, we have to say in hindsight, but based on the information they had at the outset it seemed like the correct decision - which is why Nintendo appears to be trying harder to tailor their product - this time - to the third parties' desires, offering them more of what they want. Hopefully in the process they won't alienate the end-consumer, because the biggest success in the industry comes from appeasing both.
