Since it doesn't seem like we are going to see anything new SwSh related at the end of May, it is probably safe to assume the start of main updates after the initial announcement for a given main series game has shifted to June. This is probably because GF now considers the release month(that is, November) to be the final pre-release month as well, as retail sales have been declining, and games have been releasing on late November, meaning there isn't much of an issue of a game leaking after going gold for GameFreak anymore.*
This follows on the start of early movie information about the starring event Pokémon shifting from February to April to now seemingly May(hard to say for M22, since we don't really have an event here, but Armor Mewtwo seems to be analogous due to merchandise).
*The less likely possibility is that release month is shifted to December for SwSh, but I doubt that.
