It'd be weird were it to come back. Of course it'd be changed in some way to be fresh again, but we'd still have the name BIONICLE there and obviously recognize it. If anything the story and mythos will have to be streamlined for new audiences. Because I have the feeling that the vast story behind the series will be intimidating, ya know? Making it tough for someone to get into it due to not being around since the start. A fan is a fan regardless though. New or old, if you enjoy something that someone else enjoys, that's great! If you know a bit more than someone else, or you know less, that's great too! If BIONICLE does come back, it'll be something else.
