I think it's actually less confusing than this generation, the difference is you're just used to this, so you don't think twice about it, but if I knew nothing I would be a little confused by stuff like this:

NX is actually simpler for the "dumb parent" they can walk into the store and any NX game they buy will work on whatever NX hardaware their little nephew has. 

With regards to a couple of posters mentioning eDRAM, I think people would be surprised to know the 3DS even has eDRAM. The New 3DS model for example has 10MB of eDRAM. Nintendo pretty much always uses it now, so I think it will be in NX, even in the portable variant. 

Only for the sake of BC.. Otherwise single screen is not a step back at all.

They'd still have to know if they need to buy it for the NX Bros or NX Bowser. 

Or what advantage does the Bowser give you compared to the Bros. consoles?

Software would be just one SKU I think. It just works on all three machines. Same thing as buying a PC game, you don't have like 10 different versions of each game and then have to choose the one that works on your particular hardware rig. 

One is portable. One is a mini-console that has average graphics. One is a pro console that has higher end graphics. 

I don't think that's really that difficult for the layman to grasp. 

I think "what the hell is the different between a 2DS, 3DS, and New 3DS?" is probably more of a head scratcher. At least the three hardware models above would be clearly different from a physical POV. 

Still think you have one console too many. Thought you had the Bowser to entice home console third party ports, which we can assume few will support. I don't see what value that one still adds for twice the price, it's just prettier graphics.

Since it's the same software. The leading port would be on the lowest common denominator, in this case the handheld, so gameplay design will be limited by it. The jump from 720p portable to a console at 1080p would also be enough for the average. Two SKU's which are portability vs graphics, you gain nothing by adding even prettier graphics option if the software is the same.

Keep the trio simple. Handheld and home consoles, with mobile on the side. Maybe include QoL products in there too.

We accept multiple handheld variants, I think we can try two different console variants for a change. It's just a matter of on this board, if it's a slightly new idea, most people game traditionalists can't wrap their head around it. 

It's very hard for Nintendo to make one single console that makes everyone happy given their market position and their need to always provide a family-centric option (which then alienates core gamers and teenagers). 

I say forget it. It's not 1988 anymore, one size does not fit all people, give them the choice, if one SKU doesn't sell very well, well then just phase it out, no big deal. It's up to the consumer to decide whether they care enough about 1080P with higher end lighting/textures and are willing to pay the premium for it. For a 30-year-old hardcore gamer in Seattle, maybe that's what he wants. For a gamer in Tokyo who just want to play Splatoon 2 ... that mini-Nntendo console sure looks good. 

And truth be told Nintendo DOES have two console variants right now, pretty much every retailer still carries the regular Wii on top of the Wii U. So even that is not technically true, Nintendo does not have just one console right now. If you walk into a store today, the "Nintendo section" is Wii, Wii U, 2DS, 3DS XL, New 3DS, and perhaps even some regular 3DS dead stock. That's two consoles, and like four (lol) handheld revisions. That's not simple at all. 

XBox 360 and PS3 aren't going anywhere either, those will be sold next to the XB1 and PS4 probably for another two years minimum. What I'm suggesting is trimming down this:

Wii, Wii U, 2DS, 3DS, 3DS XL, New 3DS XL, Amiibo. 3DS games don't run on Wii or Wii U (duh), Wii U games don't run on Wii but Wii games run on Wii U. One N3DS game so far doesn't run on 3DS, 2DS, or 3DS XL. Amiibos work on Wii U and New 3DS, but not 2DS, 3DS, 3DS XL without an adaptor and not on Wii at all. Simple right? lol. 

down to 

NX Portable, NX Mini-Console, NX Pro-Console, Amiibo. All games and Amiibo are supported by which ever you choose. 

they would get the next mgs console exclusive(releases on iphone, nx, android and steam)

idk what even eDRAM is, also the Wii U different things are just SKU's, its just different games, thats not that confusing, if a kid wants a Wii U or NX they would know what games they want and look for it. I gotta admit the 3DS line-up is complicated. but still the NX bundles or what the OP described them as can be confusing, i think nintendo wants to make it even easier, JUST ONE thing that will be a big hit.It would spread much faster aswell if it only was one thing.

The television wouldn't have one. The controller with a screen is staying. Going back to a single screen set up seen on every other platform for 30+ years isn't being "fresh." It's not time for change in that reguard. Dual screen stays on both the handheld and console.

Crisis averted.

No, mostly for the sake of gameplay.
