The Pokémon Company has announced it'll be sharing more information on Pokémon Sword and Shield's Expansion Pass - presumably with a focus on the game's second expansion, The Crown Tundra - tomorrow, 29th September, during a new Direct-style presentation.
In a bout of largely needless mystery, The Pokemon Company promises that tomorrow's broadcast, which kicks off at 2pm in the UK/6am PT, will feature "updates for you about upcoming the Pokémon Sword Expansion Pass and Pokémon Shield Expansion Pass".
Given that one half of that expansion pass, The Isle of Armor, has been out since June, it doesn't seem totally unreasonable to assume that, surprises aside, the vast majority of tomorrow's livestream will be focussed on its second component, The Crown Tundra.
