I'd also like to add that the ride was to be solely in WDI's hands from June 2007 to February 2008. Unfortunately, Ops had other plans...forcing WDI to throw curtains around and have the thing opened for christmakwanzakuh.
WDI was never able to finish what was planned. But ops wasn't the only reason; Siemens had to dump some more funds in to the project as well.
