I think the key to NX if it's going to have any success is it must become an ecosystem that works for everyone ... like STEAM does.
Nintendo's problem right now if you boil it down is there are three audiences (a Triforce if you will, lol) that they cannot ignore, but making one hardware that makes everyone happy is futile. So what's the solution? A scalable platform (NX) that can address all of Nintendo's needs and complete the Triforce:
1.) Kids/family crowd - Ah yes, there's nothing like being 8 years old, getting your first Nintendo and playing Mario is there? Nintendo always must have an eye on this market. It's in their DNA.
PROBLEMS: Hardware has to be cheap for parents to bite, and kids prefer the portable/bite-size form factor.
2.) Japan - Nintendo can't let go of Japan because well they're a very Japanese company. They love Japan and can't just let the console business die there. But Japan doesn't love consoles anymore. Solution? Something that merges the home console and portable concept.
PROBLEMS: Japan needs something new, a "hybrid" system that can play really hardcore games but still be portable could be the solution. At minimum it could stomp out the issue of the PS4 in Japan for Nintendo, with the Japanese market so frail, Nintendo needs to hold as much of it under their umbrella as possible, so the PS4 suddenly get lots of Japanese games and picking up sales is not good for Nintendo. NX Mobile Console could put a real dent in that.
3.) The American/Western Gamer - Try as they might, Nintendo still can't just forsake the American gamer. But American gaming is increasingly become more and more about the home console for any type of game that involves buttons. The home console reigns supreme here so it's very difficult for Nintendo to accept just leaving this huge section of the market even despite their lack of success with it lately.
PROBLEMS: You cannot make a "kiddie console" or a "cheapo" console for the US/EU markets. They will not accept it. And the traditional handheld is waning in the US/EU very fast. Also Western developers simply won't support underpowered systems in any serious way. We can bang our head against the wall about that all we want, but it's not changing, and no/little Western support, means no/little chance of success in the West.
In a lot of ways a unified platform (NX) can solve all of these problems, because as Mr. Iwata said, the number of form factors can increase and still have good game support by virtue of shared games . NX Pocket (for kids/budget portable players). NX Mobile Console (for Japan/new hardware concept). NX Home Console (for US/EU). Of course people from any market are free to enjoy which ever version suits their needs/budget best.
