I don't see how Nintendo is repeating the same mistake as with the Wii-Wii U transition unless you believe the release timing was wrong and not the lack of (mass market) appealing software back then.
It was a culmination of a few things and I’m only going to comment on the Wii to Wii U:
At the end years (plural) the Wii was still getting first party games, however they weren’t big games or big enough to make a difference. People can argue “oh but I bought the xenoblades and the donkey kongs and the skyward swords, etc” which hit during the final years. But, the general audience
did not care for those in a significant way to matter.
I looked through the Wikipedia list, and what released in 2010 and 2011 of note is this from Nintendo and l:
Super Mario Galaxy 2
Metroid Other M
Super Mario All-Stars
Kirby’s Epic Yarn
PokePark Wii: Pikachu’s Adventure
Donkey Kong Country Returns
Wii Party
There was also a version of Golden Eye 007 released
(2010)
Mario Sports Mix
Kirby’s Return to Dreamland
Mario & Sonic at the 2012 Olympic Games
The Legend of Zelda: Skyward Sword
They also had Fortune Street that had Mario characters in it developed by SE
(2011)
I only focused on the first party because, to many, the Nintendo system is driven by the first party and the third party is simply a bonus. It is not the draw, it is not the crown jewel. It is a bonus and nothing more. There’s a significantly higher percentage of a user base from Nintendo that would buy a new Mario than to buy say, a Dragon quest. There’s a significantly higher percentage of people that would get a new Zelda than to get any game from level 5 these days.
Simply put, the first party is what makes a Nintendo system otherwise it has nothing to draw a crowd in. Third parties are simply a bonus, an extra feather in a cap, to have an an option for someone or to be a definite purchase for others.
So, when people are comparing the Wii to Wii U to the Nintendo Switch to the eventual Nintendo Switch-Next, I think they are comparing the lack of
notable first party on the systems to carry out the
next year and a half. Nintendo, so far, hasn’t announced anything but people are confident they’ll have a whole slew of titles to pan out the next year at least and another direct later to pan out more titles to fill the switch up before the next system launches.
Though, my own criticism of this is that filing the switch with too much leaves the switch 2 vulnerable for games. People will point to third parties, but again, people don’t buy the system for third parties mainly. They buy it for first parties and third parties are simply a bonus.
One of the issues with the Wii U early years was the droughts, the really bad droughts besides unappealing software, it was barren. It had its share of third parties which left. But those didn’t save the system.
On top of that, people are expecting a Nintendo to do even a light cross-generation at the minimum, unless Nintendo has a whole catalog of new software titles to sell on not only the switch that they worked three times over anyone else in this industry to create, the Nintendo switch 2 will have no notable or any realistic period of cross gen. Why? Because there’s literally not going to be enough titles and enough manpower to actually
deliver that if they want to just deliver a bunch of games for Nintendo switch right before a successor launches.
I know they have been expanding for the past couple of years, however, Nintendo is not keen on doing any acquisitions of any notable degree for the here and now, they also have not expanded significantly enough to actually facilitate this. The fruits of that current expansion they’ve been doing in-house will be seen and felt by 2028 which is basically the midpoint of a Nintendo switch 2 lifecycle.
There’s also the other aspect that I have not mentioned here at all, that’s Nintendo 3DS. The 3DS
robbed a lot of resources away from other systems, and caused the death of two whole consuls, technically three, but that’s expected of the DS systems. Henceforth I’m not including it.
The Nintendo Switch can,
emphasis on the word
can as
a possibility not a guarantee, end up being the Nintendo 3DS to the Nintendo Wii, and Nintendo Wii U of this situation, the Ninte do Switch-Next. What do I mean by that? It should be self-explanatory, but if it was not clear enough, that just means it could mean that the Nintendo Switch might end up being a system that robs the Nintendo switch 2 of necessary resources especially for helping it pad out its beginning years to give consumers a reason for why they should even bother buying or purchasing this new system.
Otherwise they will continue staying with their Nintendo switch, and have no reason to buy a new system because a lot of titles are still hitting the Nintendo switch.
It’s more about balance, than anything. If they push too much in one direction, they get a very filled system but, a barren new one. If they push too much in the the
other direction, the effectively kill the current system of any notable legs and leave it dry but have a plentiful system to sell off to you.
