Fall Guys: Ultimate Knockout may soon receive content based on Fortnite.
This is evident from recently added code to Fall Guys. The generally reliable FNLeaksAndInfo reports that the code mentions Fortnite, as well as Fortnite characters Peely, Cuddle Team Leaer, Llama, Ripley and Bunny Brawler.
A collaboration between Fortnite and Fall Guys has not yet been officially announced. FNLeaksAndInfo suspects that an announcement may take place around Easter, due to the report from Bunny Brawler.
Fortnite X Fall Guys will be coming in the future!

Some new strings were just added to the Fall Guys content system:
fortnite_01 - Llama
fortnite_02 - Cuddle Team Leader
fortnite_03 - Peely
fortnite_04 - Bunny Brawler
fortnite_05 - Ripley#Fortnite
Both games are among the most popular battle royale games at the moment. Both games also regularly have unlockable content based on various other franchises, so the collaboration is not inconceivable.
