Pokémon Sword & Shield are not due to be released for another two weeks, but leaked copies are out in the wild and spoilerific information is already out there on social media. The Galar Pokédex has seemingly been revealed and if it's legitimate, then we know which Pokémon didn't make the cut.
Spoiler warning: though not 100% confirmed, the information below seems legitimate and may spoil the contents of Pokémon Sword & Shield.
It seems like Junichi Masuda has done his Thanos click and turned a great number of Pokémon into LCL. A thread on Resetera has collected the information from the various leaks of the game and outlined the complete Galar Pokédex in Pokémon Sword & Shield.
