I wouldn't be too sure about that:

Iwata, January '13:  "Last year we also started a project to integrate the architecture for our future platforms. What we mean by integrating platforms is not integrating handhelds devices and home consoles to make only one machine."

Kinda at odds with what Eurogamer is suggesting, at least in that there is only this handheld device and no console.

PS4 graphics in a portable form factor in March 2017 is a physical impossibility. A laptop has far more room to breathe in terms of size, heat generation, and power consumption than a portable. Resolution isn't the only issue either; it won't be able to submit enough polygons, it won't have enough memory to store all the textures, etc.

I'm forced to agree with fatslob here, you're being way, waaaay too optimistic regarding NX.

Yes it's true he said that, but a full year later in January '14, he hedges against this and says they may only need one form factor:

Iwata, January 2014:

"Still, I am not sure if the form factor (the size and configuration of the hardware) will be integrated. In contrast, the number of form factors might increase. Currently, we can only provide two form factors because if we had three or four different architectures, we would face serious shortages of software on every platform. To cite a specific case, Apple is able to release smart devices with various form factors one after another because there is one way of programming adopted by all platforms. Apple has a common platform called iOS. Another example is Android. Though there are various models, Android does not face software shortages because there is one common way of programming on the Android platform that works with various models. The point is, Nintendo platforms should be like those two examples. Whether we will ultimately need just one device will be determined by what consumers demand in the future, and that is not something we know at the moment."

You can see there to start with Iwata is now no longer sure if the form factor will be integrated (it's an open question now). Then he finishes by saying he doesn't know if they need only one form factor entirely. So that means something happened between Jan 2013 and Jan 2014. 

My guess is NX started off as a multi-hardware concept, and Nintendo actually even built multiple prototypes through out 2013 and 2014, but the hybrid model was so much more compelling to them that they decided to go fully behind the hybrid/integrated concept. 

That doesn't surprise me either. A hybrid console is something I can totally see giving Nintendo's R&D staff a raging boner moreso than a vanilla shoe-box stationary console that they're probably bored of making. The hybrid prototype likely quickly became the darling of their R&D labs. 

You certainly could be right.  Still, there's a new leaker out there currently making the rounds who goes by "Happy Nintendo Fan" who's claiming that there is indeed a dedicated home console that is x86 and features an FPGA (field programmable gate array) chip to help with the extra processing muscle.  Whether this guy is truly legit is anybody's guess but supposedly he's been vetted by a couple of sites including Gaf as having sources at or very close to Nintendo.  In any case, here's a vid on the subject from Studio Q (formerly Pretendo):

i was more questiong the people, if this device was made by Sony or even MS would the people praising it care? 

but those are the big guns. they are pretty much Japanese AAA games.

Which begs the question will this system get those Japanese AAA games?

You'll get no argument from me in that regard and thats great...for Japan. That doesnt really do much for the prospect outside of their native land especially since the NX might not even get the games that people outside of Japan kinda care about. Your FFs, KHs, REs etc.

It could indeed be a very tough sell in the West, but I'm withholding judgement until we know it's price and the sort of software it's getting.

While I doubt FF will get there, RE: Revelations was first released on 3DS and then ported to consoles. There comes a point where people begin to realize these hand helds are rapidly approaching console games in terms of quality; maybe not graphically, however. Monster Hunter for example, is a complete console game on a hand held. This console may not get ports, but to think it cannot get its own worthy titles from some of those franchises (Final Fantasy aside) would be a little prematurely pessimistic.

Wut.

It will only get the ports if the console sells in sufficient quantities.
If it bombs like the Wii U, don't expect anything outside of the initial launch window.

For instance the Wii U missed out on the likes of most Frostbite powered games that even ended up on the Xbox 360 and Playstation 3. (Everything from Battlefield 3 to Dragon Age: Inquisiton.)

There is also more to rendering a game than simply just lowering the resolution too, some effects simply don't get less demanding by dropping the resolution.
Tegra also has different performance characteristics than AMD's APU's, especially when it comes to more modern graphics techniques, where AMD typically comes out ahead, that will hamper porting efforts and you may see some serious cutbacks to graphics.

What kind of Gflop?
What is the relationship of Gflop's and Resolution?

Geforce 730M cannot be compared to Tegra on flops alone.

Anything less than 720P on a mobile device is unacceptable in my eyes.

The Wii U is actually a little bit faster than both the Xbox 360 and Playstation 3, when games are made it's way.

It needs to be allot faster than the last gen consoles though, they are showing their age and games tend to look extremely terrible on those platforms now.
You also need orders of magnitude more performance just to double the graphics quality now as well.

No.
I don't think you understand what "flops" is truly about.

You cannot compare two different processors on flops alone.

For instance if the Geforce 730M has superior bandwidth, larger caches, more polymorph engines, more ROPS, more TMU's, then the Tegra could be built at 16nm, have twice the Gflop's and still be slower.

Makes 3 of us.
