Are Mario Kart Fans Right About a Donkey Kong DLC Tease?

According to GameSpot, Nintendo fans are convinced a Mario Kart World DLC announcement is imminent, based on datamined evidence from the Nintendo Today app. The datamine, viewable on Mario Wiki, reveals that an intro animation for Donkey Kong villain King K. Rool is set to feature in the app on December 15. This marks Nintendo’s first official acknowledgment of K. Rool’s surprise role in the recent game Donkey Kong Bananza. Fans connect this to the fact that the Japanese voice actors for K. Rool and another Bananza boss, Void Kong, are credited in Mario Kart World’s launch credits despite their characters being absent. The timing of the K. Rool animation, arriving just days after The Game Awards 2025 streams on December 11, has led to speculation of a DLC reveal at the show. Mario Kart World launched with the Nintendo Switch 2 to massive sales but has had no post-release content announced.

Connecting the kart dots

So, is this just hopeful thinking? Honestly, it’s one of the more plausible fan theories I’ve seen in a while. It’s not just one random clue—it’s a chain of them. You’ve got the mysterious voice actor credits at launch, which is a classic breadcrumb. Then you have Nintendo preparing to officially spotlight a major “spoiler” character from a hit new game in its news app. And that spotlight happens to fall right in the window of the industry’s biggest year-end showcase. You start connecting those dots, and a picture forms. It’s not a guarantee, but it’s sure not nothing.

The case for a DK expansion

Here’s the thing: a Donkey Kong Bananza-themed expansion makes a ton of sense. Mario Kart World, while fantastic, launched with a roster that felt… safe. The Donkey Kong representation, in particular, is pretty lean on costumes and deep-cut characters. A DLC pack could introduce K. Rool and Void Kong as new drivers, add tracks based on Bananza’s wild levels, and finally give DK himself some fresh looks. Nintendo has a history of using The Game Awards for reveals, and what better way to promote two flagship franchises at once? Basically, the business logic is there, and now the circumstantial evidence is piling up.

A hungry fanbase

Look, the fan reaction here is driven by one simple fact: people want more. Mario Kart World was the Switch 2’s killer app, selling nearly as many copies as the console itself. And since launch? Radio silence on the DLC front. Nintendo has supported it with quality-of-life patches, like the recent one adding custom item rules, but that’s just maintenance. The community is starving for substantial new content. This theory, whether it pans out or not, is a symptom of that hunger. They’re scouring credits and datamining news apps because the official channel has been quiet. You can’t really blame them.

Wait and see

Now, we have to be a little skeptical. Voice actors get credited for minor, unseen roles all the time. The Nintendo Today app animation could just be a cool, standalone nod to a popular game. But the timing is awfully convenient. All eyes will be on The Game Awards on December 11. If a Mario Kart World expansion isn’t shown there, the December 15 K. Rool feature will feel like a weird, anticlimactic coincidence. And if it *is* shown? Well, those fans will look like geniuses. I think we’ll know very soon which scenario is true.
