Wait a minute, Disney is going to build a multimillion dollar land themed to Star Wars, and the tentative plan is to keep the existing Star Tours attraction disconnected from this? That doesn't make much sense in my mind.
A thought occurred to me while writing this though. If Disney were to keep Star Tours separate from the new SWL, I could see Disney attempting something similar to what Universal has with the Hogwarts Express. Imagine Star Tours being the "space port" on Earth with shuttle service to the new SWL area. The last sequence on the simulator would be a new scene where the guests arrive on proposed planet that SWL is themed around. Following the ride, guests are rerouted around the back of Muppets through current backstage areas to the grand entrance of SWL. This way, Disney keeps Star Tours, continually updates the ride sequences, saves money on repurposing/demolishing the existing building, and creates the atmosphere of actually traveling at light speed to get to another galaxy.
Thoughts?
Lots of people have suggested that idea but there is no evidence it will happen. Logistically it would be difficult to make the connection behind Muppets, and personally I think if they really wanted them connected they would have sacrificed Muppets and built SWL directly adjacent to Star Tours. You also need to consider that a similar situation exists in DL, albeit the ST is further from the land, so a connection there is not really possible. It will either standalone or be re-themed there.
