I have read a few things about the new site themes and tried to follow the updates, but I have not yet read anything whether our "Save the Robot!" campaign has been heard or not.
Shortly, the new site theme is to be rolled out on "beta and undesigned" sites. Which does (probably) not include Worldbuilding, as it is neither Beta and is quite obviously designed.
Are there any news regarding the site theme for worldbuilding?
I did not manage to find anything on Meta.SE. Except for that plan in June was
August - September: release to the remaining sites. As we have more details we will update individual communities in their local meta.
September is not over yet, but I have not read anything about Worldbuilding up until now.
