I mean Super NES after NES I'm sure was fairly successful. 

Yokoi is overrated big time. Most of what the Game Boy was isn't even attributable to him, he wanted to make some weird disposal toy type thing like Game & Watch for the Game Boy, not the interchangeable portable game machine that it became, he had to be yelled at and embarrassed to finally renege. The Virtual Boy was quirky and all, but honestly terrible, lol. 

Yamauchi's big, big mistake was opting to agree with cartridges over CDs, but I think he was pressured into that decision by designers like Miyamoto. 

What i like about Furukawa is that he is expanding Nintendo's development base when the rest of the industry is contracting and doing layoffs, he is even building a massive new EPD building. That shows that unlike other businessmen he has a long term strategic view rather than only thinking about maximizing short term profits by doing layoffs. Instead he is betting on a beefed up Nintendo delivering even more first party output in the future.

Switch 2 is also the best value Nintendo hardware in ages.

It's actually a very powerful little piece of kit that can run an astounding variety of games even right up to modern gen big budget open world games with ray tracing like Star Wars Outlaws and Indiana Jones.

For $450 you're not getting much better than that if at all from any tech manufacturer these days and they continue to have very reasonable promotions like free game deals.

They are adjusting game pricing downwards too. All the whining about Nintendo trying to rip people off is really overblown. The Wii was a rip off, they took a Gamecube that they were selling for $79.99 as of 2005 and just moderately overclocked it, added some cheap RAM, a different controller and charged almost 3x the price for it. The system couldn't even run GameCube tier games at lower 720p HD resolution at a time where most people were buying HDTVs.

THAT is a rip off, lol.

You do realize that without Yokoi, there would have never been a GameBoy, no? In the initial manufacturing of GB product, there was an error which made the screens appear much too dark to see anything. Yamauchi, already skeptical on the weak specs of the system, reportedly responded by demanding that the GameBoy be scrapped. But Yokoi fought and eventually got his way. GameBoy was his brain child, as was Game & Watch and marketing NES as a FamiCom.

Curl, just ignore the user. He’s never got anything positive to say, and if anybody still finds a $450/500USD price point on hardware to be “too much” for a base model, then you need to look at the competition as well as the commercial success of NS2. Especially as of lately.

So you are holding the near nixing of the GameBoy against Yamauchi the president that brought Nintendo into the video game space in the first place?  Did he not end up being swayed into the GameBoy in the end providing Nintendo with another console pillar? Being able to be swayed seems like positive in this scenario since that path lead not only to the portables but also Pocket Monsters amongst other software. He could have dug his heals in but didn't.

Nice topic by the way. On said topic, my 2 cents would be: That while I am not versed well enough in the history, that Furukawa has not screwed up yet and ridden the wave he was placed on.  He hasn't wiped out yet but he looks a little shaky where Nintendo's software output is concerned. Considering how closely they have been playing their software cards to their chest I could be wrong about that.  He could be saving cards back for when the console sales momentum begins to wane. It is just too early to tell with him.  I think your question comes too soon to be answered well or fairly, but that is part of the fun of a hot take that should be a bold prediction.  

Yamauchi fucked up big time with the N64 and Gamecube handing over the bulk of the market to Sony, but on the other hand, he built the company into a gaming empire that at one point controlled like 80% of the market, and was ultimately strong enough to weather the downturn and make a comeback thanks to the foundation he created, without which they may have gone the way of Sega or Atari.

Iwata likewise messed up with the Wii U big time, but he did set up the phenomenal comeback that followed before he passed.

Furukawa's real test is coming.

But the NDS was still Yamauchi's idea.

Incorrect.

Satoru Ikada (who gets no credit) is actually more accurate the "father of the Game Boy". Yokoi's wanted to make a successor to Game & Watch and not a portable NES/Famicom like device with interchangable cartridges and 3rd party games, what Yokoi wanted to make would've been much cheaper and more disposable. He had to be yelled at by Ikada to finally give up control over the project and from then on Ikada basically made what is the Game Boy. Yokoi's main contribution really seems be in the end to give the Game Boy a crappier quality screen (whoop de doo). At 10:54 into this video:

Most people don't understand Yokoi didn't want cartridge games at all, it was basically supposed to be a Game & Watch, but you could replace the cheap screen overlay for games. It was meant to be basically a very simple, disposable thing that could play like basic Game & Watch style titles like a Ice Hockey or Donkey Kong most likely but nothing past that complexity and was meant to be replaced after a few years. The Game Boy would have sucked if he had got his way.
