Carsland was meant to be DCA's exclusive new area for an underachieving park. I know you know that and II'll take a neutered Cars Land and a real Star Wars Land that only includes one new ride over a real Star Wars Land that only includes one new ride and nothing.
know it would be about 5-6 years after CL opened by the time it got here, but anything short of a full RSR and the rest of the land (minus Luigi's) would be a disappointment in comparison. I don't know exactly what was on the table, but just demo work won't be cheap for that area. Knowing TDO i'm sure they tried to cut every corner in the books.
I don't want something just dropped there which is pretty much a permanent addition for the foreseeable future just to have something new. The land is very valuable to the park right now and to me, a neutered Carsland isn't worth it.
