There will be a HUGE update at some point in the year, yes (so many errors right now, there's even some french left on a few pages).
Right now I'm working on another game using the same system, where you can play anything that comes to mind. It'll be called LIMITLESS. Once it's done (I'm 90% there, writing wise), I'll do the Hogwarts update.
If you like the system itself, it's based on the game "Hopes & Dreams" by FariRPG, an industrial-magical runepunk rpg inspired by Arcane.
