Super Nintendo World, a Nintendo-themed area at Universal Studios in Japan, had its eventful opening back on March 18, 2021. While the grand opening of Super Nintendo World was a massive success, Nintendo doesn't seem to be shying away from an idea of a Donkey Kong-themed specific region, as an expansion to Super Nintendo World.
Given neither Nintendo nor Universal Studios Japan has yet spoken about the Donkey Kong expansion, we do not have a lot to confirm at this point in time. However, recent leaks from credible sources have found some promising images that suggests DK could eventually arrive to Universal.
Super Nintendo World has its own app, and some smart data miners managed to dig out various resources related to Donkey Kong. The images shown in the tweet below were discovered back in December of 2020. The images are strikingly similar to the Mario-themed stickers and stamps that Universal Studios visitors collect during their ventures in the park.
If you're an OG of the Donkey Kong games and have played a lot of it, then the door shown in the image down below might be familiar to you. The door can be found in a newly constructed area at Super Nintendo World. Albeit closed, it hints at the Donkey Kong expansion very strongly.
