It'll be fixed in the future, Nintendo's Masuda said.
Nintendo’s Junichi Masuda addressed concerns that classic Pokemon were cut as a result of the franchise’s move to Switch by confirming that the Pokedex would be fleshed out — or is that re-fleshed out — in future iterations.
“You can look forward to seeing Pokemon that don’t appear in these games appearing in different regions in future games,” Masuda told the publication.
Masuda also pointed out that Pokemon that don’t appear in Sword and Shield can still be stored in the Pokemon Home cloud service heading to smartphones in 2020.
“We’re really designing it as the place for all of your Pokemon together, so it’s really important for the future of the franchise, and it’ll be more than even Pokemon Bank as a place to gather all your Pokemon together in one spot,” Masuda said of the upcoming app.
