Hollow Knight: Silksong co-directors Ari Gibson and William Pellen talked about the sequel's release strategy. According to them, the release date was determined literally a few weeks before launch.
To some extent, it's probably frustrating. It wasn't a very controlled release. We didn't even know the exact date until a week or two before the trailer was released. Everything happened quickly, and fan expectations also influenced it.
Gibson added that the team worked until the very last moment, rushing to finish the game.
The trailer announcing the release date has garnered 17.5 million views at the time of news publication.
