Game Freak claims it is not reusing Pokemon models in Sword/Shield
In recent days, Game Freak has come under fire for various grievances fans have with the upcoming Pokemon titles, Sword and Shield. Following the controversy of only a select amount of Pokemon being in the game at all, Game Freak was then criticized for reusing animations and character models from previous Pokemon games. However, these claims appear to be untrue, as a previous interview with Junichi Masuda and Shigeru Ohmori confirms that Game Freak has had to create every Pokemon model in Sword and Shield "from scratch". The June 2019 interview, which went largely unnoticed due to its lack of English translation, was also not referenced in the "official response" from Game Freak two weeks ago, regarding the Pokedex issue.
Due to the nature of the Nintendo Switch's better hardware and smoother framerates, the 3DS-era Pokemon models and animations were unable to be directly transferred over to engine that Sword and Shield are running on, so the team over at Game Freak had to remake every Pokemon model. This was apparently especially difficult for the team, who has had their normal amount of developers split between two major projects: Sword/Shield and Town. During the development of Sun and Moon, Game Freak was "barely able to" import all 809 Pokemon into that game with a full dedicated team as it was. This, coupled with the daunting task of balancing each and every Pokemon was what led to Junichi Masuda deciding to "choose quality over quantity", when it came to choosing which Pokemon would make it into the Galar Dex. In the interview he says, "The decision is sad. Of course I wanted to bring all the Pokemon in if I could do it, but this was a decision I had to make eventually".
Masuda even joked about the matter responding that the Pokemon that won't show up in the game are thinking, "This region is too cold. I think I'll stay at home this time."
When it comes to the matter of adding subsequent Pokemon in post-launch updates, Game Freak says that they are considering the idea, but are undecided at the moment. He also further explained that the Dynamaxing and Gigantamaxing features require additional 3D models from each Pokemon, and are not simply resized versions of their existing assets.
