Screamscape doesnt post message board speculation. So if he is posting this info, then its probably from a credible source, and is actually happening. It also appears that he is aware of what the in-car show will be, but I wouild imagine that is more speculated at this point, which is why he didnt post that as well.
Like I said, I want to know how much this is going to actually cost me. If I have to spend a lot extra to travel between parks, I may never ride it.
