Btw these were the numbers for the last Pokemon games on the first half in the year after their releases:
Pokémon OmegaRuby / AlphaSaphire 207.780
Pokémon Sun / Moon – 527.862
Pokémon Ultra Sun / Ultra Moon – 215.281
Pokemon Let's Go Pikachu / Eevee - 230.134
All those games were released almost at the same point as Sword and Shield (3rd friday of November), so I guess it's a fair comparison
Sword and Shield is doing slightly better than Sun and Moon that was selling ~4k weekly at this point (and Sun and Moon had a much bigger user base from 3DS)
In other hand, Sw&Sw weekly sales seems on pair with Let's Go, which is not that good as this one is a main entry and Switch as been selling like hotcakes in the last months (and of course, Let's Go don't have a DLC)
