I know we've been "told" Midyear Mayhem will be in June but I believe that was just a post on the forums? We're 7 days into June so its be cool to get some idea when and if that's still happening. I won't be on June 10th-17th so really hoping it's at the end of the month.
I can usually get some idea from the crown store showcase but it's not much help beyond saying it will be sometime this month.
