Wii U suffers on lack of support that could satisfy any form of demand. If Nintendo can get the usual Japanese handheld support, now with the added bonus of making it an easy sell on console internationally, the NX home console will get more support through that. And Nintendo's repeating issue in the past has been ensuring a steady stream of software on all their platforms.If Wii U is any indication (and I think it is), the market isn't asking for a new Nintendo home console anywhere.
On this topic there's this fitting quote by Iwata (Source):
Iwata in Oct. 30 said:Our output speed is, of course, important. At the same time, we believe that maintaining the active use rate of our platform carries the same level of importance. I think you can relate when I say, when we keep touching a video game system, we tend to look for the next software we want to play. As a result, it becomes easier for consumers to purchase their next games. On the other hand, if the game system is out of our daily routine, we tend to lose interest, making it less probable that a new game will come to light. When we look back at previous hardware that did not succeed, they always failed to maintain the active use rate. On the contrary, the platforms that sold a lot established their respective positions in the market not because they had a lot of games – many games were offered for the hardware as a result of the hardware selling well and it establishing itself as a lucrative platform for publishers to sell their software on. We believe that the real key is whether the hardware is able to maintain the active use rate.
