Hundreds of Pokémon from other generations will be introduced in Pokémon Scarlet and Purple, although others will continue to be left out of Nintendo Switch.
The next November 18th will be the premiere of Pokemon Scarlet and Purple to start the ninth generation of the license developed by Game Freak. Given the proximity of the date, it is expected that there will be some official news in the coming weeks, although by and large, many more details of the new deliveries should no longer be released. The last thing that has been known is the revelation of Bellibolt, the frog Pokémon, in addition to numerous leaks that point to new details of the final evolutions of Paldea’s initial Pokémon. Now, they may as well have met Pokémon that will be left out of the Nintendo Switch ecosystem.
And this does not mean that the Pokémon that you will see in the list are left out of Pokémon Scarlet and Purple only, but that they are about species that have not appeared in any Nintendo Switch title and that can only be available through Pokémon Home. With the introduction of new Pokémon from other generations that are added this time, the list has been significantly shortened, but these 27 Pokémon are still not available on the Nintendo hybrid system.

Thus, these Pokémon will not be present in Pokémon Scarlet and Purple, in the same way that they were not present in Sword and Shield or in the remakes of the fourth generation. It is especially noteworthy that many of them are fifth generation, the one that should receive the next remakein case Game Freak and The Pokémon Company work on it.
297 Pokémon from other generations will return in Scarlet and Purple
Although these 27 Pokémon will not be part of the Pokémon Scarlet and Purple Pokédex, there are another 297 from other generations that will. The total number of species that will be available in the Paldea region will be 400although it is very likely that is expanded by DLCs to be released later during 2023. This also opens the possibility that some of the Pokémon mentioned above could return from the ostracism in which they find themselves at the moment.
So it will play wait until next November 18 to find out if all these details end up being confirmed by launching Pokémon Scarlet and Purple exclusively for Nintendo Switch.
