Looking at various things over the internet, it doesn't look like Orlando's event will have the New Line characters return. (However, they are returning for Hollywoods event)
But I have to say, Orlando's event is shaping up very good. It looks like this year is the one where the creative department is really able to have a larger budget.
For anyone that's been to previous HHN's, expect a return of Body Collectors and a 3rd incarnation of Scary Tales.
