Wow so here’s some interesting news that game freak just slid under the radar during the treehouse yesterday: you will not be able to transfer all of your Pokemon from Home into Sword and Shield. If a Pokemon is not in the Galar pokedex (which apparently is about 800 of them?) you will not be able to transfer that mon into either game. This is a big change for the main series games.
At first the thought was well maybe they just needed to cut down some development time to make November but maybe the next games would add back in the missing Pokemon and the national dex. However, later on Masuda clarified saying that from now on this is a new Game Freak policy for all Pokemon games going forward.
So basically, every game from now on will have a selection of which Pokemon can appear in that game and it will vary from game to game.
As you can probably imagine, the internet is taking this well.
