"We know that it's part of a unified platform of systems, we know that it's meant to absorb the Wii U's architecture, we know that it's sharing a library of games between a portable and a handheld"

No, that's just bullshit you made up and keep saying as if it's a fact.

No it wouldn't be. Them not being the same doesn't mean them not having overlaps, and they have plenty. I don't even think they'd need to wait three years. They could successfully launch an NX 2.0 two years later, and an NX 3.0 another two years later. That's a benefit of a unified, persistent platform. The original NX wouldn't become obsolete for years, so old owners wouldn't need to feel burned.

The iPhone 4 came out nearly five years ago, and only recently has it begun to show its age. Still works with 99% of apps on the app store, and now anyone who hasn't upgraded can buy the most state of the are iPhone this year with the 6S and transfer all their information and apps to the new device with no hassle. A new NX would be the exact same way. You buy the NX in 2016. By 2018, the NX 2.0 comes out. It's advertize as having better hardware, more powerful, and comes with an improved NinOS 2.0. People with the OG NX get the NinOS 2.0 for free on the day the hardware launches, so the only reason to upgrade is if you want the latest tech. This will mostly appeal to people who hadn't gotten the NX yet. By 2020, the NX 3.0 rolls around. NinOS 3.0 rolls around. Same thing. Incremental update in power and maybe a minor new feature/better screen for controller, etc. By this time, more people with the OG NX will feel the need to upgrade, as the system will probably be showing its age a little compared to the NX 3.0, but it can still run 99% of the games, so you can always just opt to get the free OS update again. Again, 3.0 will appeal to newcomers, but this time, it'll offer a far greater appeal to people ready to upgrade as well. And with the membership program, all your downloads and information will transfer via your account and the cloud, so it'll be like you never even changed systems. They could literally do this forever, and slowly gain an audience more and more attached to these accounts.

It would be genius. It would also be copying Apple, but Nintendo hasn't been shy about doing so in the past.

EDIT

Oh. I see what you are. Nevermind. You're ignored.

Apple products sell to kids as well. Nintendo products being cheaper would make selling these things easier, not harder. Nintendo can easily change their branding to appeal to whatever audience they want to. They already proved that with the Wii, where they made the deliberate choice to appeal to a more casual audience in their ads for it. A similar rebranding for the NX could have them appeal to whatever audience they want.

And there isn't any "specific audience" that buy hardware upgrades. 90% of people who will buy the iPhone 6S this year will be people who owned an iphone 5S or lower, not people who bought the 6 last year. People harp on about there being a "new Apple product every year," but the reason that works is because the older products don't immediately become obsolete at the introduction of 1, or 2, or even 3 updates. People who bought a 6 aren't wishing they had a 6S. People who bought a 4S are wishing they had a 6S. Nintendo can pull off a similar thing with the NX.

Release a new NX every two years and a new NXDS every year, and allow the older versions to download the latest OS updates, and they'd rake in money.

That would actually be a really bad idea. It would do so much to hold back their games and would basically kill 3rd party support forever. It would be like if Sony said that any studio making a PS4 needs to also make a PS3 version of the same game.

Edit: Plus, who's buying the NX2 if all of it's games also launch on the NX they already have?

I think people are looking at it from a wrong angle as I can see what he's trying to say, people are having a tricky time grasping it because they're thinking of NX as a standard console when it seems it will be closer to steam and IOS combined only with its own set of devices, the games don't have to be BC with previous hardware but they'll always be part of your library for future hardware is what he's saying. 

People who haven't bought the OG NX, duh.

And no it wouldn't. It hasn't stopped iOS from becoming one of them most dominant gaming platforms on the planet, and it hasn't stopped Steam from growing exponentially. It wouldn't be like if Sony asked devs to make a PS3 version of anything, because the PS3 is completely different in architecture to the PS4. They literally have nothing in commont but the brand and similar shaped controllers. The NX 2.0 and the like would be much less drastic and be designed around making that kind of thing a non issue. That's the whole point of a unified platform. To make one game playable on multiple hardware interfaces. If it can work between something as drastically different as a handheld to console, there is absolutely no issue in making the same thing work on a console with hardware only two years more advanced.

It would completely change way people think about game systems. Right now the NES is associated with these games, the SNES with those games, the N64 with this, the GCN with that, ect. With the NX, it will be more like Steam and iOS. Steam is accociated with all PC games. iOS is accociated with all app store games. With the NX, Nintendo will just be accociated with "eshop games" or "Nintendo games" as opposed to "NX games." That means games from the NES to the NX 5.0. That's why I think referring to the NX as an "X gen system" is ultimately as stupid as calling a PC an "X gen platform." The NX will be generationless, like PC and mobile currently are.

And PS Now/the future of xbox live will be generationless as well. Gen 8 is the last traditional generation.

Pretty much. Basically, if Nintendo released a N3DS-level upgrade every year for the handheld and every two years for the console. The only reason to upgrade is to get better hardware because you can still play all the latest games on your old tech for years just fine, and you'd be getting a new major OS update every year as well, so it's not like the hardware would remain stagnant. And when you're ready to upgrade, you can just transfer your account and all your games over. That's good for the dedicated consumer. If you waited years to get the NX, you can jump in at any time and not feel like you're buying aging tech by buying the latest iteration, yet still have access to all the games of all the prior systems, because the software isn't tied to the hardware, but the firmware.

I could see it honestly. The current way of doing things is not doing anything for Nintendo so why keep playing by those same 30 year old rules. 

Most of the next-gen leap will be eaten up by the need to probably run games at 4K anyway. 

So yeah sure I could see a new NX 4K model in 2019 that runs games at 4K res with some added graphical effects, but the same games could still run on the old NX models just at lower res, lower effects. I don't really see the problem with that. 

I'm not sure it would be that powerful honestly. Like, it should be. I'm just not sure I'd buy that it will be that soon not when the PS4 and XBO won't and it won't really need to compete on that front.
