NX Portable-between Xbox 360 & Wii U in terms of specs, has Wii U level visuals on a 5" screen at 540p, $199.99 at launch

NX Console-between Wii U & Xbox One in terms of specs, plays all the same games at 1080p with better AA, $199.99 at launch

Thank you, very good post. Nintendo simply can't make a console that's between PS4 & PS5 in terms of specs and a seperate handheld that's between Xbox 360 & Wii U in terms of specs and give them each adequate support of exclusives, it's simply not possible and Nintendo-published software is and always has been the main reason to own Nintendo hardware.

A single device that allows me to play all Nintendo-published software? Hell ya that sounds amazing, I don't like having to spend $500-600 on hardware to get the full Nintendo experience like is required this generation.

Generally I agree with this but I'd maybe amend it a bit

NX Portable - Wii U level graphics at 540p-720p, even some more modern lighting/shader effects/more RAM, 6 inch screen at 1280x720, $229.99 launch fall 2016 (300 GFLOPS approx)

NX Console - 3x the portable (900 GFLOPS approx), so not far off from an XBox One. Runs Portable Games at 1080P with some added effects. Has 1-2 new gimmick inputs (head tracking visor?). $199-$229, 2017 launch (?)

I think the initial form factor of the portable will more like a mini-tablet, than a pocket handheld. Tablet form factor will give them more size to disspate heat from a relatively decent chipset and include a larger battery. Smaller form factor can come later when 16 or 14nm shrink is possible. 

If they have things like Zelda at launch they can probably get away with the bigger launch price too -- that will ensure the hardcore Nintendo fans are buying at the start ... whereas Nintendogs couldn't sell a $250 3DS, everyone was waiting for the "real" Nintendo games to show up. 

There isn't really a reason not to. It's a win, win situation.

The major challenge will be backwards compatibility but that can be sacrificed for the greater good.

Personally I don't mind it. I only use Nintendo consoles to play exclusives at this point, as Nintendo made sure that multiplats suck on their platforms. The more Nintendo games I get on a single platform, the better for me then.

It's a whole different thing though when you think what's better for Nintendo. One thing is certain, they have to change what they have been doing the last 10 years. At this point they are between a rock and a hard place. On one hand mobile is destroying their handheld market - I'm 100% sure their next handheld won't get anywhere near 3DS sales. On the other Sony and MS pretty much eliminated them from the home console market (though in reality it was Nintendo that made itself redundant).
Now they somehow have to save themselves, they either need to pick up the glove of Sony/MS or do something different that will work this time. Making games for only one platform is a must if they keep on ditching 3rd parties. If I was them I'd just make a regular console that would get 3rd party support and a Vita-level handheld with easy porting, that would get all Nintendo software. Unfortunately I'm afraid they won't deliver on the power front due to this whole Fusion concept, which will forever force them to the role of "the second, less important console".

They wouldnt use x86 but probably ARM

I think this is what they will need to do. At least work closer with smaller 3rd party studios in the west that have got HD experience.  The reason why I think that is because they will get further and further behind the competition and will become a nastalgia box for gamers who like Nintendo games. that audience will continue to shrink every generation. 

For starters I think they coudl work with a engine developer to help them come up with a auto scalable engine that will work on both systems. Crytek may be a good choice for that as they are desperate for work atm and their engine isn't too bad, so I am sure they would be happy to make a new one, or even guys makign the unity engine. 

The problem is NIntendo are too stubborn to try that so I think your vision of fusion will be the only viable option.  I just wish their fusion was a bit more powerful. 

Well if it makes you feel better I do think the next Nintendo handheld will be quite powerful. Like the N64 or PS4 of handhelds if you will.

With Nintendo being able to get at kids/cheap parents with smartphone/tablet devices and the New 3DS being able to stick around for a few more years to serve the "budget handheld" role ... you probably would want to go back to a higher end mentality with handhelds now to greater contrast smartphone games vs. traditional handhelds.

So you know ... I mean lets say the mobile NX chip is 350 GFLOPS or so ... throw three of those in a box and really Nintendo games would probably look just like any PS4/X1 game for the console variant. 

Because it'd fail case closed. The next Nintendo handheld won't be powerful as an Xbox 360 and Nintendo's next console will be more powerful than a PlayStation 4. Trying to combine these two power gaps would spell utter disaster.

Well, people said that about the Wii motion controlls as well. With the moble technology evolving as fast as it does, we could really be surprised with the power of the next handheld.
