Incredible that you asked that question, as I was just speaking to a friend of mine who works "at the park" just yesterday, about this very subject. She said, though it's not "official" right now, that they have started to relocate the employee parking over by CA, and have told the employees that in 2015 the Star Wars land will be opened there, and that they "may have" a tunnel going from Tomorrowland to SW land, or it may be a shuttle, like "Star Tours" that will transport you from Tomorrowland, thru "space" and then touchdown in SWland, which sounds like a great idea. I don't know how they would pull it off like that. The employees were told that it will be a "third land", with a separate admission required, just like WDW!
She also told me that they were planning to relocate Star Tours to that land, and put the shuttle transportation area where Star Tours is located right now. Might be just another rumor, or just a bunch of BS, but that's what I was told.
Oh, yeah, I almost forgot, she's kind of mad because the "exec" that was reporting this news stated that the opening was going to be on a certain date in 2015, which just so happened to be the SAME day as the opening of the "Harry Potter" area in Universal Studios, Hollywood! Her family and her are BIG Harry Potter fans, and they are all really ticked off about it!
Anyway, just a rumor right now....
