Will Ninty next home console be nothing but another iteration of the handheld? So no you cant say Ninty hasnt given up on the home console business, I love the excuse though keep them coming. Wiius failure is held up higher because people are desperate to shit on anything Ninty related. Thats why I mentioned ps3s failure and ps4 not going anywhere near ps2, because all of that was overlooked while nintys handheld business does the same and gets shitted on for it. You cant even prove Vita really is it for Sony, yet you had no problem pushing it. Because yet again you want to just sweep Sonys issues under the rug. All i see from Ninty these days is take as many franchises that were once home console exclusive over to 3DS as quickly as possible. Sony supports Vita the best way they can, 3rd party support. Its still selling enough to beat Wiiu, some would even argue Vita as better support. So tell me why are you so quick to believe sony is leaving but Ninty isnt? I know, because the agenda of Wiiu being held up higher needs to be supported.

1. Fix your grammar. I understand we're not writing in an English class so mistakes are to be expected. However, it shouldn't be a chore to read through a response.

2. Improve your reading comprehension. Where did I try to "sweep" Sony's failure with the Vita under the rug? I acknowledged they failed in giving the device the first party support it needed to succeed and shifted all of their focus onto the PS4. What am I supposed to? Repeatedly lament on the fact that they failed with the Vita? On a system that they themselves don't even acknowledge. About a future handheld, you're right that I can't prove there won't be another handheld from Sony. However, with how Sony has treated the Vita, it's a fair assumption to make that they won't make another. But who knows, maybe I'm wrong and they're crazy enough to do it again.

Also, you say the Wii U's failure is held up higher because people are "desparate to shit on Nintendo." That might be true for some people, but there are quite a few Nintendo fans on this site that aren't blindly slurping anything Nintendo puts out like yourself. They understand Nintendo's commercial failure with the Wii U and how damaging it is. They don't grasp for pathetic excuses and lash out at everyone when they have the "audacity" to acknowledge it.

Hey guys, let's keep the discussion healthy, ok? This already earned someone a warning and we don't want this to end up badly.

But it better now then never. Good luck Nintendo

You can deny it all you want, but the statistics speak for themselves. 3DS is on track to be Nintendo's worst selling portable besides the Virtual Boy, Vita is a disaster, and the portable market has collapsed by over 60% from last gen.

Some should check they language there's Kid and teen coming to this site. If a personal opinion made you that mad (just ignore it) putting oil on the fire made you same has the other user period! 

Maybe if I said 'games for handheld' and 'games for home console' it would be clearer to you. Yes, in theory, with the right tech any game could be put anywhere. But games for handheld and games for home consoles do exist in Nintendo's current generation of devices, simply because the right tech to put them anywhere will only be available in their next generation of devices. (See Nintendo source later on in this post to support this point)

Games in the Mario Kart series are pretty generic and work well on both portable and home console with their 3 minute races and 15 minute trophys. Indeed, there's been a MarioKart released for every home console and portable. But other games haven't been designed that way. Take Luigi's Mansion 2 Dark Moon, for example. It was designed specifically with 'gaming on the go' in mind, and so ended up with a different play structure from its home console predecessor.

"By making it so that it was a separate mission structure, players could [also] play the game for a short period of time."- Yoshihito Ikebata, LM2 Supervisor, Nintendo

"We altered the main ghost ‘fishing’ mechanic to match the controls available on the 3DS. The new system of capturing required us to change the way the basic ghosts behave about the mansion." - Bryce Holliday, LM2 Director, Next Level Games

So Luigi's Mansion 2 Dark Moon can be described as a handheld game, or game for handheld, because it was designed as such in terms of gameplay, to be played on a handheld console.

Clearly, it wasn't obvious to you before, going by the quotes below.

Nintyfan90: "How much more could Ninty's plats become more integrated? 3DS and WiiU already share alot, " http://gamrconnect.vgchartz.com/post.php?id=7791219

Nintyfan90: "You never actually said anything that's proves the plats aren't quite alike. What's so different about their OS? They are both pretty barebones and neither has much the other doesn't." http://gamrconnect.vgchartz.com/post.php?id=7791294

Ninyfan90: "Please tell me what's different besides the obvious power difference?" http://gamrconnect.vgchartz.com/post.php?id=7791294

However, I'm pleased that you're now enlightened, although it seems from what you've said below, that you've not fully understood any of the sources I gave you:

No, quite the opposite. The quote I provided was to demonstrate that the difference between handheld and home console is not just about power, it's about architecture. The quote is about hardware (which includes the Wii U and 3DS), the problem Nintendo faces with the platforms being so different, and what they intend to do about it. Since it appears that you may have misinterpreted that quote, I'll bullet the main points for you.

• Handheld and home consoles had to be developed separately, because of their technological requirements. This led to completely different architectures and different methods of software development. It requires a huge amount of effort to port games from home console to handheld and vice-versa.
• If the transition of software from platform to platform is easier, it will help solve the problem of game shortages in the launch periods of new platforms.
• We are going to create a system that can absorb the Wii U architecture. When this happens, home consoles and handheld devices will no longer be completely different, and they will become like brothers in a family of systems."

In short, the hardware isn't there yet. This means that there is a difference, a difference that Nintendo has had to merge two divisions to address. In fact, if you read Iwata's entire response in full (you can find it in his answer to Q5 in the link above) you will see that they can only start doing this with the next system. (This also supports my first point in this post about the right tech not being there).

I am talking about games made in the future - games that will be made for the NX, games that are made by 1st party, 2nd party and 3rd party that will need minimum effort for them to work on both platforms. This is expected to help get rid of 1st party game droughts, (according to the source above) and entice 3rd party support because of the potentially larger audience that the combined platforms would offer. That is, of course, if the NX is presented as a handheld and a home console with shared architecture.

I would assume that games that were developed specifically for Wii U, 3DS and earlier systems may always be more difficult.

No, it doesn't. See second bullet point above.

The arguments I have given are based on

1) The plans Iwata outlined for unifying handheld and home console architecture in a new system during an investors Q&A session in early 2014, and

2) the hypothesis  that the NX will be Nintendo's next generation of both handheld and home console. 

But as I have already stressed before,  we still have no idea what form the NX will take. It could be just a handheld. It could be just a home console. It could be one of each. It could be a single machine that works as both types in some way. It could be a suite of different machines that you mix and match. It could be none of these. All we know for sure is that it is a dedicated games console with a 'brand new concept'.

Therefore nobody can answer your questions, or comment on your speculations in this last point, because there is not enough information yet. We will just have to wait and see.

 I haven't denied anything, this matters way too much to you simply because you dont like seeing Ninty bring their best to the portable side and shit on the home console side. You only want the fall of handhelds, so you have a reason for Ninty to go all home console. So enjoy Metroid Prime on Wiiuuu.....oh yeah. Ninty wont let handhelds fall, so keep on begging for WiiU ports. While they keep on supporting handhelds to the best of their abilities. Smartphones killed handhelds but for some "odd" reason we cant figureout why they are killing home consoles in Japan. Oh and heres my favorite part, "3DS is on track to be Nintendo's worst selling portable besides the Virtual Boy" while "WiiU is Nintendo's worst selling home console". You see the difference, 3DS still has very minor chance while WiiU could be done later this year and will be forever cemented as Nintys worst. Sounds like Ninty is putting their eggs in the right basket.

When I say generic, I mean universal in terms of how the gameplay works for both types of console.

From what we've seen from the quotes, the whole point of unifying the architecture is to make the behind-the-scenes porting and adapting between consoles quicker and easier. It could lead to better quality adaptations with the variations you describe; I have no doubt that Nintendo's developers will take advantage of that. It would certainly enhance what home console games could bring to handhelds (and vice-versa), which I believe was one of the main concerns raised in the OP. But according to Iwata's comments in that Q&A I mentioned, it appears this would only be possible from NX going forward.

In answer to the question, and based on the sources and quotes, I think a fusion of architecture is absolutely necessary if Nintendo want to have a handheld and a home console, and have them both be a success. It is a potential saving on time and resources, which could result in greater efficiency in producing 1st party games, and a greater attractiveness to 3rd parties through exposure to a wider audience.

Nintendo is not about just chasing 3rd parties. Their brand and IP is far too strong for them to drop, and anyway, they're going all out to put their IP out there in mobile apps, theme parks and so on. But okay, if you want me to entertain the hypothetical situation where Nintendo were only creating the NX in order to chase 3rd parties,  a fusion of architecture across both platforms would still be necessary to maximise the chance of 3rd party support, now that the technology is available for them to do it.
