Before the game series was cancelled by Disney, a fourth installment was quite elaborately planned and worked on extensively. The name would've been "Disney Infinity 4.0: Kingdoms" and it would have primarily been based of Disney's animated film Aladdin. It was to be developed by United Front Games who are associated with working on the Marvel expansion of Disney Infinity 3.0 as well as Sleeping Dogs, ModNation Racers, and Halo: The Master Chief Collection. It seems the game would have had a feature where characters of unrelated universes (ex. Star Wars, Marvel, Zootopia, etc.) can be played and seen in the Aladdin-based Story mode, which would have been unique to 4.0. (Although it does bare some resemblance to the Toybox Takeover feature in the previous game.) Pre-alpha footage of the game was uploaded to Vimeo in November of 2018 by a throwaway account, revealing the game's existence.
