I met John Lasseter today at Epcot. He and his wife are doing beverage seminars for their winery as part of the Food and Wine Festival. You can meet him yourself if you go to the Festival Center where he should be signing bottles of wine (priced at $30 - $ 50), taking pictures, and answering questions from 3pm - 3:30pm on the 17th. They sell the wine directly for $24 - $40 so pricing isn't ridiculous. The seminar is from 2pm - 2:45pm and anyone can watch in the back, though space has long since sold out. He talks mostly about wine, but adds in some stories about Walt, Disneyland, etc.
Anyway, I asked him, "So is Cars Land coming to Florida?" His response was, "I sure hope so."
Take from that what you will. He also talked for a brief moment about New Fantasyland, which he was not aware was open to guests yet.
Here they are presenting.
