I think the Cosplay Roadshow is similar to the Tokyopop ReCon where they hold events around the UK at different times. I've messaged them if it's going to be like a Tokyopop ReCon and if it is then I'll [or somebody else] will post a separate thread and will keep the dates updated much like the ReCon thread~
If there's a set date and location then I'll put it up on the list on the front page.
London Expo: Noel Vermillion [Blazblue]; Rise Kujikawa [Persona 4]
Hyper Japan: Sheryl Nome [Macross Frontier]
