I think that at this time, the park has already come far enough for us to backtrack on this, unless there is a radical government change and a new govt does not see any value in the park.
Futhermore, by the time we changing government, the project should be 30% done, so stalling is a bit hard and would also result in law suits.
The country by now should not be operating like our universities where a project comes to an abrupt end once the associated lecturer departs or is forced to depart.
