Is there a planned toy story attraction at disneyland?
Quick Answer
Yes, there is a planned Toy Story Land attraction at Disneyland Paris, which originally opened in 2010 as part of the Toon Studio area in what was then Walt Disney Studios Park.
Explanation
Toy Story Land is an existing themed land at multiple Disney parks worldwide. It opened in Disneyland Paris (then Walt Disney Studios Park) on August 17, 2010, at a cost of €79 million. The land has since expanded to Hong Kong Disneyland (opened November 17, 2011), Shanghai Disneyland (opened April 26, 2018), and Disney's Hollywood Studios in Florida (opened June 30, 2018, following its announcement at the D23 Expo on August 15, 2015). While the question asks about Disneyland specifically, the existing Toy Story Land at Disneyland Paris represents the planned attraction referenced, rather than a new or future project at the main California Disneyland park.
