Pokemon Sword and Shield producer Junichi Masuda released a new statement regarding the National Dex issue and how players are unable to bring the Pokemon not in the Galar Pokedex into the game.
Check it out below:
Thank you to all of our fans for caring so deeply about Pokémon. Recently, I shared the news that some Pokémon cannot be transferred to Pokémon Sword and Pokémon Shield. I’ve read all your comments and appreciate your love and passion for Pokémon.
Just like all of you, we are passionate about Pokémon and each and every one of them is very important to us. After so many years of developing the Pokémon video games, this was a very difficult decision for me. I’d like to make one thing clear: even if a specific Pokémon is not available in Pokémon Sword and Pokémon Shield, that does not mean it will not appear in future games.
The world of Pokémon continues to evolve. The Galar region offers new Pokémon to encounter, Trainers to battle, and adventures to embark on. We are pouring our hearts into these games, and we hope you will look forward to joining us on this new journey.

The issue originally came up when it was revealed during E3 that only Pokemon present in the Galar Pokedex would be able to be transferred in from the upcoming Pokemon Home service. Later, it was further clarified that this is likely to be the state of matters going forward, especially as more and more Pokemon total come into existence.
Pokemon Sword and Shield will come to the Nintendo Switch on November 15, 2019.
