Here is a message from Luminous Productions on the delay:

We have made the decision to move the release date of Forspoken to October 11, 2022. Our vision for this exciting new IP is to deliver a game world and hero that gamers across the globe will want to experience for years to come, so getting it right is extremely important to use. To that end, during the next few months we will focus all of our efforts on polishing the game and can’t wait for you to experience Frey’s journey this fall.

Thank you for your understanding and continued support. We look forward to sharing more about Forspoken with you soon.
