I wouldn't think that KI would take it down unless it becomes a pain to maintain or parts are unavalible for it, a la KC. Also, i don't think a park would want to invest money in buying a coaster that is 20 years old. With the money it would take to dismantle, transport and then reinstall you could probably buy a new coaster. And I believe that Arrow built The Vortex based on the terrain that it sits on so another site maybe out of the question.
