To explain, originally when it was announced back at D23; the original concept art of Toy Story Land included the original version of the Slinkey-Dog Coaster to be in the land, and a higher amount of detail. When the SOA was closed off, the concept art changed to a revised version of the Slinkey-Dog coaster being just a Multi-Launching coaster, with what seemed to be a shorter layout trim; and the cutting of a lot of scenic pieces that we're from the original Concept art.
It's been rumored for a good amount of time now, that they may be cutting more out of DHS's TSL but there hasn't been any reasoning as far as I've seen on other forums outside of OU. But that doesn't relate to the MSHI thread at all, as that can be discussed on the Toy Story Land thread..
