I've heard several reasons why Kalos would be/could be/should be in Sword and Shield and all of them are valid (to a degree) but none really convinces me since...well we know who GF are we saw their methods in latest years.

However there's one thing that makes me wonder. Why did GF show us a full map of the Galar region already? They havent shown legends, they havent told us the release date even but for some reason they decided to show us the entire region...just like that this early. Even fucking USUM Alola map came late on in the campaign and here we have the whole thing just bam at the very beginning. Strange
