Has disney announced any new attractions featuring toy story characters?
Quick Answer
No, Disney has not announced any new attractions featuring Toy Story characters beyond the existing Toy Story Midway Mania! attraction.
Explanation
The only Disney attraction that brings Toy Story characters to life is the interactive 4‑D ride called Toy Story Midway Mania! It was designed by Walt Disney Imagineering and launched in three parks: Disney's Hollywood Studios and Disney California Adventure in 2008, and Tokyo DisneySea in 2012. The attraction is based on the Pixar franchise but there is no evidence in the provided sources that Disney has announced any additional or upcoming Toy Story-themed attractions. Therefore, as of the information available, Toy Story Midway Mania! remains the sole Toy Story attraction in the Disney theme park portfolio.
