Oddly enough, reports are being made all over the web about Miyamoto stepping down completely from hardware development and focusing on Games, being that this isn't the first time he's stepped down from a bigger position, I don't completely understand what the fuss is all about honestly. From what we now know, Miyamoto will not be working on the new NX console itself but more-or-less games that will play on it. Nintendo has worked by the code "Software sells hardware" for years, so I think that Miyamoto focusing on games is a smart move, he's responsible fore making some of Nintendo's best video game characters and franchises like Mario, Link & Zelda, Star Fox and a few other Nintendo characters too, so focusing on games is probably best for him in this business. Another thing I'd thought I'd mention is that some people still think...
the NX will be a console only (not work with smart devices) and the Wii U will not be in production once it is made. However Mr. Iwata claimed when he first announced the NX that they would continue making software for the 3DS and Wii U while in preparation for the NX console, which now may not be released until 2017. The new console also seems to be able to work with the Wii U and 3DS consoles, as well as with Smart devices (according to Nintendo's graph), so I wouldn't be planning on pitching the old console and just getting the new one when it comes out, if I were you.
"Though I cannot confirm when it will be launched or any other details of the system, since I have confirmed that it will be "a dedicated video game platform with a brand new concept," it should mean that we do not intend it to become a simple "replacement" for Nintendo 3DS or Wii U."Iwata @ the Third Quarter Financial Results Briefing for Fiscal Year Ending March 2015 Q&A
