I think the Carsland rumor has gone back and forth so many times, I'm not sure Disney even knows what they are doing. They need to bring in something BIG that will help round out the park because Star Wars is going to be overwhelming. Carsland would fit, it can be reproduced with minimal design costs.
Well, I've heard many say that SWL was going outside the park for a long time, so it's not new news .... but the BIGGER bloggers just wouldn't get their heads around it, so talk just stopped. I've said since announced when talking to others that SWL made ZERO sense in the Streets of America area, it only made sense outside the existing park boundary. AND Disney promised a 14 acre EXPANSION. That says outside the park. Again, the major bloggers kept drawing it inside the park with their color boxes.
PS We all love to think that the DIS boards or WDWMagic are the Cat's Meow but there is way more info happening on twitter and elsewhere. I get way more information on stuff like this from places other than DIS.
