I could see PKI doing a giga-coaster in the future, but not a strata-coaster. With Dropzone & the Eiffel Tower there I don't think height would be a problem. They've got plenty of acreage. I also don't think money would be a factor. The only thing I can think of would be their whole thing with catering more to the whole family. Meaning, their obsession with building more family-friendly attractions. Winning the golden ticket "again" for best kids area won't help that dream either.
Well actually that depends. On whether SF wants to make that type of investment into one of their parks, while the others sit and wait. That certainly isn't out of the realm of possibilities, especially for known money makers like SFGadv or SFMM. Next year is out of the question, but who knows what will happen after that.
Blackpool pleasure beach in England used to have the worlds tallest. The pepsi big one, and has stated they want the record back (no surprise there) i dont believe they have any height restrictions at all, unlike most british parks, so no problems there.
They are due a new coaster soon, and apparently they have been looking at Intamin rocket coasters and S&S thrust airs.
There's tons of parks that potentially could do it. I would venture that half the major parks in this country without height limit issues would be able to find the money to do it, its just a matter of getting the investment back. What parks SHOULD do it would really be the more interesting question, but giving the current climate around coaster building, the economy in general, and having never run an actual amusement park, it would be pretty hard for any of us to speculate.
