Usually a new Pokémon generation happens every 3 years. Pokémon Scarlet and Violet were the start of the Gen 9 which released in Nov 2022. This means the earliest we can expect Gen 10 by Nov 2025.

There was a interview from the The Pokémon Company COO that addresses their awareness. "I think in general, if you look at the past, the path we've taken up until now has been this constant release, always regularly releasing products on a fairly fixed kind of a cadence, you might say. Always having these products able to be introduced and new experiences for our customers, and that's how we've operated up until now. I think we're still operating in that way, but there's more and more conversations, as the development environments change, about how we can continue to do this, while making sure that we're ensuring really quality products are also being introduced." -Takato Utsunomiya (Chief Operating Officer of The Pokemon Company)

Essentially saying that The Pokémon Company has been talking about if they want to extend their timeline to release a game a year later than usual.

There are many rumors of either:
- Legends game for Unova or Johto
- Let's Go for Johto
- Remake for Unova or Johto
- Remake for Unova & Johto (like how in Gen 2, and remakes in Gen 4, you visit the Johto region and the Kanto region).
Honestly, all of those sound amazing. Personally, I'd rather have them wait to release any Gen 5 remakes (I want quality, which is a difficult thing for the Pokémon Company apparently.).

And I'm on the high end of your prediction, cause I think they can reach 152M shipped by Dec 31 2024. Either way, it looks like a great last year for the Switch. :)

It wasn't just Sonic, the Megadrive's technical superiority to the NES and aggressive marketing gave its early sales a strong push. If it had come a year later, it would have had less time to exploit this before the SNES levelled the playing field. Launching early let them build enough momentum that it took the SNES til like 1994/5 to catch up.

I never said it would be a fatal blow that would kill Switch 2, just that it's a misstep. They would be better off transitioning while the brand is hot rather than letting it cool. It's a consistent problem with Nintendo's consoles since the N64, the inability to transition smoothly from one gen to the next.

Wii U's premature death mattered less cos Switch also succeeded the much healthier 3DS.

We do not know that Switch 2 yet has physical media, but Nintendo’s branding will lose none of its potency. Concealed within their offices, Nintendo’s marketing strategists see all. You know of what I speak, a new hybrid, lidless, wreathed in flame. Nintendo is gathering all developers to them. Very soon they will summon a library great enough to launch an assortment of digital titles upon the new Switch.

I have seen it.

The hour is later than you think. Nintendo’s factories are already moving. The nine have left Minas Morgul.

(I must stop now, I’ve leaked too much)

But what of Nintendos tax rate?  - P.S Martin

The nine - led by the Witch-King of kart racers, the one they say no racer can kill.

And while Nintendo breeds its army of exclusives, understudy Game Freak breeds an army of 10,000 Pokemon games to conquer the world of men.

2024 is set to be another 10m+ year for hardware sales and 100m+ units in software sales shouldn't be a problem either, so this still sounds like a doom fantasy rather an analysis of the facts at hand. This shows even moreso in your self-contradictory response: "Consistent problem with Nintendo's [home] consoles, but look, Switch also succeeded the 3DS, [the handheld line where Nintendo hasn't had these same problems]."

Annnnnnd now I want Middle-Earth Kart.

But Switch in 2024 is much healthier than 3DS in 2016 so that still doesn’t make any sense.

3DS shipments calendar year 2016

hardware-7.36 million, software-56.43 million

Switch shipments calendar year 2024 (estimate)

hardware-10+ million, software-100+ million

Tbh I feel like the idea that you have to launch a new system right when momentum is hot and not dead is kinda overrated. Sure I'm sure it helps a little bit especially early on launching your system when you still have good momentum, but it certainly doesn't mean much in the long run, as long as your system is appealing people will eventually buy it no matter how little momentum you have going into the next generation.
As stated earlier the awful momentum of the Wii U & 3DS going into the Switch's launch didn't at all stop the Switch from selling historically. The 3DS having high momentum isn't a good argument either cause in 2016 the 3DS only sold 7 Million, which isn't great and very small compared to Switch's annually numbers and even worse on the software sales side where many 3DS owners weren't as engaged to the 3DS that much to call it high momentum going into the Switch.

Another example is the PS1, Sony had no momentum prior in the games industry to capitalize on launching the PS1 and while it was selling slow at first, it still would go on to sell 100M units cause it was just a good system. I'm seeing some people act like it'll be suicide if the Switch 2 launches in 2025 while the Switch is dead which is a complete exaggeration. No matter when Switch 2 launches as long as it's good it'll sell just fine.

I was referring to first party support. It's once again looking like Nintendo has more or less left the building 12+ months before new hardware arrives, just as they did with the N64, Gamecube, Wii, and Wii U. 

It would've been better for both Nintendo and their audience if they'd planned this better to avoid such a drought.
