Off Kilter is being replaced by a Canadian lumberjack show. Saw the tree trunks on Saturday during the Food & Wine Festival.
Some more rumors and info about Hollywood Studios. At some point, the name is going to change to Disney's Hollywood Adventure.
The park is going to essentially be three areas.
First, Sunset Blvd that ends with Tower of Terror, Fantasmic, and Rockin' Rollercoaster will be mostly unchanged except a Tangled show may replace Beauty and the Beast eventually.
Second, Pixar Place is going to expand to the back of the park where the Backlot Tour was. The soundstage beside Toy Story Midway Mania may be used for a 3rd track to free up wait times. There's going to be a Toy Story themed kiddie ride area like they have at some of the international parks. Also, they're going to bring Radiator Springs Racers from Cars Land in California, but it will most likely be inside due to the frequent rain in FL. I'm guessing they'll do something about the similarity to Test Track.
Third, the whole left side of the park will be Lucasfilm themed. Basically everything from the front to Star Tours will be Star Wars themed.
The rest is the Frozen stuff which will be continued indefinitely after what we supposed to be a summer stint and the Streets of America primarily for the Festival of Lights. The lights are actually already up.
If you're visiting this week, Toy Story ride is Fastpass+ only.
