Chessie does seem to be the forgotten park for new rides... I guess their hands will be forced when Ramases Revenge, at the dear old age of TWENTY RUDDY THREE YEARS OLD has to finally pass over soon.
Or, they'll just leave a hole where it once stood. Or theme a maze around the old queue line a la Slammer, whilst looking on at the ride you can no longer ride, that Merlin CBA to remove.
