After nearly a full year absent of releases, it has been announced that the Creation Club will be returning soon, with the current goal being to have a release before the end of the year. Originally there was an expected release scheduled for sometime in March, but all of the new Creations were delayed due to Bethesda transitioning to remote work in the face of the COVID-19. While everything was ready, including the patch, the transition made it impossible to release it as is for reasons that were not disclosed, according to Cartogriffi, Bethesda's Community Content Manager.
Additionally, while Bethesda is planning on having a release of some of the Creations before the year is over, they claim that they did not stop development of Creations over this year, and that they will most likely have to have multiple releases due to the quantity of work done. While specific details about most of the content was not provided at this time, the Community Content Manager mentioned that an experimental Creation for both The Elder Scrolls V: Skyrim and Fallout 4 was approved that would have solely focused on a quest, instead of an item or location reward. However, with the delay, the scope of both of those experiments were raised to also feature notable item rewards.
Bethesda has chosen not to provide a solid release date at this point due to the previous delays, but we will update you when we have more information. You can read the initial announcement here. You can read a response from Cartogriffi discussing the delay here.
