Sequels are made when creators don’t have faith in new ideas and want to attract customers using existing IPs. This is especially true for sequels to stories that are already complete: there was no need for a sequel, they are just making it because the IP is popular.
Exceptions to the rule exist (Toy Story 2) but I wouldn’t hold my breath. Looking at the list of upcoming Disney/Pixar movies and seeing just a bunch of sequels (Inside Out 2, Zootopia 2, Frozen 3) just speaks of corporates choosing the “safe” route of betting on popular pre-existing IPs instead of new stories and original settings.
