The way he's explaining it here it is. It can't get any plainer than that...he clearly says that it's been 5 years that Johnny Blaze has been dealing with caring the curse of the Ghostrider that he took from the Devil and now he's trying to deal with the dark side of it....soooooooo sounds sequel to me.

ah ok so though what your saying sounds like a sequal to me i think i understand now and its like this

its a *reboot or remake however they call it* as the first movie is pretty much an origins with how it all started and at the end he goes away leaving all that he knows behind cue 5 years later as the path gets darker when he lives with this curse

now in terms of remake as im guessing its likely to be the origin is cut short youll probably get a little backstory similiar in the way of superman then cue 5 years later when the real adventure and story happens

does this make sense at all lol :P?

Makes a lot of sense that way. You know how they like to do the back stories but you can't erase him having the curse 5 years...so yes, you said it pretty good.
