I don't think you "replace" anything ... do you replace STEAM? Now you'll look puzzled at that, but that's the point. Steam in no single piece of hardware. NX should be kinda like that IMO. 

There should just be new NX devices as time goes on. 

2016 - NX Portable and NX Console launch

2017 - NX Portable Pro launches

2018 - NX 4K Console launches

It's not 1989 anymore, people are willing to accept upgrading hardware as the norm (see: tablets, smartphones, etc.)

Etc. etc. I think Nintendo may have shown what the NX is already though through this patent, which shows basically an upgradable console:

That's probably the NX IMO. And that is a pretty bold change from what they do today. 

Well if the successor of Wii U and 3DS are one in the same, just available in different form factors than Nintendo can certainly provide adequate support for the device with a holiday 2016 lineup thru 2017.

Zelda U could very well be a cross-gen release for both Wii U & NX.

EAD Tokyo release a console 3D Mario every 3 years (Galaxy-2007, Galaxy 2-2010, 3D World-2013) so a new 3D Mario available for holiday 2016 is possible. They typically release a smaller title between mainline console Mario titles (NPC: Jungle Beat, Mario 3D Land, Captain Toad) so a smaller title for holiday 2017.

Miyamoto hinted at Pikmin 4 releasing next year without a specified platform, it could be Wii U or it could be NX or perhaps both.

Monster Games releases a game roughly every 2 years (2011-Pilotwings Resort, 2013-DKC Returns 3D, 2015-Xenoblade 3D) I could see them releasing a Tropical Freeze port since the game underperformed by being on Wii U.

Retro Studios releases a game roughly every 3 years (2004-Prime 2, 2007-Prime 3, 2010-DKC Returns, early 2014-Tropical Freeze) so a new title at some point in 2017 is very likely.

EAD Group 1 releases Mario Kart roughly every 3 years (2005-DS, 2008-Wii, 2011-3DS, Wii U-2014) so an NX release in 2017 is possible.

Hal Labs releases a new Kirby title every 1-2 years (Nov 2011-Return to Dreamland, Jan 2014-Triple Deluxe, Feb 2015-Rainbow Curse) so a new Kirby is 2017 is possible.

ND Cube releases 2 games roughly every 2 years (late 2011/early 2012-Wii Party/Mario Party 9, 2013-Wii Party U/Mario Party 3DS, 2015-Mario Party 10/Amiibo Festival) so at least one game in 2017 is likely.

EAD Group 2 release 2-3 games every 2-3 years (2005/2006-Animal Crossing DS/Wii Sports/Wii Play, 2008/2009-Wii Music/Animal Crossing Wii/Sports Resort, 2012-Animal Crossing 3DS/Nintendo Land, 2015-Splatoon/Happy Home Designer) 1 game in 2017 and one in 2018 is very possible.

Game Freak releases a new Pokémon Gen every 3-4 years (1996, 1999, 2002, 2006, 2010, 2013) so a new one in 2017 is likely.

Something like this is certainly possible considering these teams typical dev cycles.

Nov 2016-Zelda+3D Mario

Dec 2016-Pikmin 4

Feb 2017-Tropical Freeze Port

March 2017-ND Cube Party game

May 2017-Mario Kart

June 2017-Kirby

August-Retro Studio's Project

October-Pokemon Gen 7

November 2017-Splatoon 2

December 2017-EAD Tokyo title (Captain Toad 2?)

That's probably the NX IMO. And that is a pretty bold change from what they do today. 

How is Reggie saying that they've already publicly announced that they're hard at work on their next home console, not any evidence of a console?
There is a home console coming. That's a fact. Doesn't matter what it ends up being called, the fact that Nintendo already publicly talked about it means it's coming sooner rather than later.
Sony, Nintendo and MS all start R&D for their next console as soon as they release one, but they never publicaly talk about it until it's closer to release. Even when Sony went out to get developer's feedback for PS4, to see what kind of hardware they'd like, they blatently denied that it was for PS4, even though it was obvious to the devs. That's just how it works.

And feel free to point out where I'm not thinking here: http://gamrconnect.vgchartz.com/post.php?id=7627167

I've done plenty of thinking about this. Probably more than most people here, seeing as I haven't seen anyone else compile a post of breaking down the situation as thourooughly as I did.
The "more powerful than PS4" argument isn't backed by any evidence though. But don't pool that together with everything else.

Nintendo also launched GBA and Gamecube in 2001.
If there are two versions of NX, they may be released in two different time frames. But that WiiU would last until end of 2017 is looking very unrealistic.

Reggie also called Splatoon  an "Action Adventure" game. He often talks bullshit. He clearly has no idea about videogames, hell, he worked as CEO of Pizza Hut before. He's just a business man doing his job. Probably he just said home console, like he said Action Adventure.

Nintendo publicly talked about the Wii at E3 2004! Two and a half year before its launch. Nintendo talked about the Wii in 2010! Two and a half year before its launch. Nothing surprising here. They'll continue that pattern. And if you're a fan of patterns (because of your GBA/GCN argument): the DS was released before the Wii, the 3DS was released before the Wii U, so....

Because Wii U is in worse shape than 3DS, both in terms of sales and games.
If you look at sales numbers, Wii U is already too low and making it wait for Christmas 2017 would just be suicide; retailers would not keep the console in shelves if they knew that 2017 would be a bare year.

Remember early 2013 when some retailers started discounting Wii U and others even stoped selling it? And this was at the very beggining where the console could still fight back. Imagine now, where it would get no new releases - or anything significant.
3DS, at least, will get the best support from Nintendo, like it has been having; 3rd parties are still backing the 3DS aswell, even if only japanese developers.
Wii U has pratically nothing to hold on to for two years.

And like Hiku told you, GBA and GC came out in the same year. So, it could happen again.
Personally, i believe Nintendo will release both at the same time.

Just because 3DS has been on the market longer doesn't mean it needs to be replaced first.

How do you propose to port a game that isnt finished yet. It takes a year of development to port a game.

This is exactly the problem i have with these theories. You think this is all easy and trivial to do. Games development takes a long time. Bringing out a system require alot of resources. This isnt done over night. Retro is the only studio i can see would have enough development time to come up with something. But if you think that NX development kits cant have been ready any earlier than in the last couple of months, you are sugesting again the development of a game in 1 year.

The Mario team did Tresure tracker last year. They have 1 year development. Time. The Mario Kart team did DLC until last year, they have 6 months development time. Pikmin 4 was announced for the Wii U. Again we are in the ports of games that aren't complete yet. It will be rushed, poor quality.

And we are still ignoring that Nintendo is not the most efficient HD developer yet. Delays all over the place. It takes a bit of a jump to think that from delaying most HD titles they will jump to next-gen in 1.5 development cycles.

Everything points for 2017 the earliest. You are forcing this preparednes for this year they just can't possibly have. Besides the fact it all comes from the assumption that the portable and home system will run the same architecture. Have you pondered that this means the portable would be more expensive than the portable system?

Although probably another fake, it's the first one with some logic behind it. Nintendo already said their next handheld and home console will have the same architeture. The most possible outcome is that the sucessors for Wii U and 3ds have around 30-40% of it's first party lineups as major exclusives, with the rest (major multiplayer titles, smaller 3d games, all 2d games) getting the smash for Wii U and 3ds treatment. The visual difference would be smaller due to the power gap shrinking and there should be cross buy and cross local/online multiplayer for shared titles. Same cross buy for virtual console titles.

Sharing the whole library is not only impossible but also a terrible business decision. That's because exclusives are what value a platform.

Because I think the Zelda team has been working on an NX port for some time now, similar to how they got Twilight Princess out for Wii's launch.

How about read what i said, because I just showed u that 2017 is likely for all these games based on the teams standard dev cycles. The jump to HD didn't stop them from releasing games in a similar time frame.

Yes the Mario team did Treasure Tracker in late 2014 but like I said, they always release a smaller title between console Mario titles, 2007-Mario Galaxy, 2008-Jungle Beat Wii, 2010-Galaxy 2, 2011-3D Land, 2013-3D World, 2014-Captian Toad. They always release a title between console Mario titles and still have maintained their 3 year console Mario cycle.

Do u really believe the entire EAD Group 1 was working on DLC, fuck no, that's reserved for a relatively small team while the main team works on the next project. Like I said, Mario Kart has released every 3 years, 2005/2008/2011/2014, a new installment in 2017 is very possible.

And once again u are making things up, Pikmin 4 was never given a platform, it could be Wii U or it could be NX, maybe even both.

I don't think NX is going the be a massive leap over Wii U, I wouldn't be surprised to see it just be a moderate boost similar to GC-Wii.
