Yeah, I don't think the copyright owners would be thrilled with USH announcing the remaining 5 mazes on the same day, especially since I'm sure more people will focus on the popular ones over ones that most won't care for. Though as far as my memory can reach, I know 2013 we had one of the latest maze announcements with El Cucuy being released at the end of August. There might be other years with later announcement dates, but worse case scenario, maze announcements stretch into late August, along with the website launch.
