All absolutely good points.
They may also want to do something with it but aren't able to allocate the funds to it yet. If they have a good summer, or their mid-year review shows a better than expected result, they may be able to allocate additional funds to a retheme. This may be why gold coaster was such a short notice period - they may not have known it was able to fit in the budget until the last minute.
I agree this ride needs change (not removal) but with so much going on across the entire park - Tiger Island redevelopment, Rivertown, extensions to Ocean Parade, the Flyer in Main Street, the ongoing works in 'Dreamland' and the recent work on GD and the Train, if you add that to the retheme of Gold Coaster, install of Taipan, the removal of log ride, TOT, Wipeout and Buzzsaw, there is very little of the pre-TRRR park (outside of the wildlife area) that remains untouched. It's clear they're working their way down the list, so i'm happy to be patient.
