No, plain and simple.
Ok first off, too all the people who want Zelda on Xbox/Playstation, the reason you want this is because Zelda on Nintendo consoles are just that good in fact its a general consensus that ALL Nintendo first party games are generally really really good, you know why that is right?
Because Nintendo are using their own tech.
This is why first party titles are generally better all across the board, because these devs know the tech better than anyone else. If Nintendo was to go third party, we no longer have that assurance, Nintendo spend years R&Ding all their systems, if they are given another companies system and work to their specs it is going to feel forced.
Secondly, Miyamoto may as well quit, Iwata and Nintendo R&D will essentially make a console to his standards, his desires and why wouldn’t they? If the guy who makes you Billions upon Billions every where wants something then no doubt the company will do it. Does anyone honestly think that Miyamoto will feel even a fraction of the inspiration he usually has by looking at Xbox One and PS4.
Thirdly, this goes directly to all people who are demanding Nintendo go third party, once again you are saying this because you want to play Nintendo games. But I ask you,
Why not just BUY a Nintendo console?
Nintendo consoles have generally ALWAYS been cheaper then their competitors and yet you go and buy more expensive boxes and then complain that another company isn’t on your machine. Yet you could buy a Wii U, play Mario, Zelda, Smash, Metroid etc and third party developers would actually want to develop for the system because people are buying it.
and lastly, remember the Nintendo of the 80’s/90’s? Remember the kind of MONSTER that company was, well let Nintendo go third party and they will be a nightmare even EA would be scared off. This company is worth more than most third party developers in Japan combined, Sega, Capcom, Namco, Tecmo, hell maybe even Square Enix! Nintendo could go on a massive spending spree and be a rutlhess monsters to Microsoft and Sony, having so much money and influence they could form the Xbox Two and PS5 into a device made for them, just look at what EA did to the Xbox One with it’s DRM bs.
Now all of that is just speculation, but what isn’t is the magnitude of this company. Nintendo is HUGE, they are not giving up because of just one lackluster console, they are not Sega and this isn’t the Dreamcast.
So again, Nooooooo!
