Quoted from solarvalue:They seem to be alternating widebodies and narrowbodies. So that would mean narrow-body Toy Story is next, seeing as the original leak was right about DI and POTC and also mentioned Toy Story and the Muppets.
Next Toy Story movie release date is 21 June 2019
I don't know if any more Muppets movies are planned?
If we're following a pattern it was 2 wide, 1 narrow.... Pirates is wide, so next one will be another wide #2
