It could happen in the not-too-distant future, it seems. As spotted by @PushDustIn over on Twitter, 7-11 stores are advertising the Booster Course Pass in Japan. The advertisements are only focused on the first wave, which is already out, with details on future waves still unclear. Interestingly, however, a message on the top right of the advertisement for staff members notes that the ad shouldn’t be displayed after July 17, suggesting that it might be outdated soon, and that an announcement for the second wave of DLC tracks could be imminent.

Previously, the names of the Cups that will be added to Mario Kart 8 Deluxe will all waves have been revealed, while datamining has also potentially spilled the beans on a number of upcoming tracks.

Mario Kart 8 Deluxe is available on the Nintendo Switch. It has sold 45.33 million units as of earlier this year.

7-11 is advertising the course pack (note that it says you double the number of courses in Japanese, nothing about wave 2). I think we should see a reveal sooner than later. pic.twitter.com/qpRtTBiUdp

As pointed out by @Mr.Nantendo on Twitter, dataminers have been able to dig into the files in the recent Mario Kart 8 Deluxe update, which includes an updated banner showing various images of previously unannounced courses, suggesting they will be added in future DLC updates.

These tracks include the likes of Sydney Sprint (Mario Kart Tour), LA Laps (Tour), Mario Circuit (SNES), Koopa Cape (Wii), Rainbow Road (3DS), Vanilla Lake (SNES), New York Minute (Tour), Sunset Wilds (GBA), Maple Treeway (Wii), Merry Mountain (Tour), and Vancouver Velocity (Tour). Seemingly, evidence has also been found for other tracks, including Waluigi Stadium (GCN), Shy Guy Bazaar (3DS), and DK Summit (Wii).

Meanwhile, Twitter user @fishguy6564 has also managed to dig into the game’s most recent update and dig out information on the games that most future upcoming tracks will be originating from. As seems to be the trend based on the first wave of tracks and the aforementioned datamining, a large number of them seem to be coming from Mario Kart Tour.

Recently, the names of all upcoming DLC cups for Mario Kart 8 Deluxe were also revealed in the update. Read more on that through here.

Of course, until such time Nintendo officially confirms details of what tracks will be coming in as part of the remaining five DLC waves, take all of this with a grain of salt. We’ll keep an eye out for new details though, so stay tuned for more updates.

Looks like we got a datamine leak after all. Courses on here include:
– Sydney Sprint (tour)
– LA Laps (tour)
– Mario Circuit (SNES)
– Koopa Cape (Wii)

Can you see any more? pic.twitter.com/uv6bGadUye

I need to go sleep but the cowboy stage from GBA (Sunset something) and Maple Treeway are also there

I have awoken. Looking around it looks like people have also seen Shy Guy Bazaar, DK Sunmit and Rainbow Road Wii? Not sure how they know its Wii specifically though

Here is a showcase of all the cups with potential prefixes. We have not confirmed if it is grabbing this information from garbage data. pic.twitter.com/3yW46Ms1D5

While it’s been previously confirmed that the first two cups, arriving on March 18, are called Golden Dash Cup and Lucky Cat Cup, thanks to a new update, Mario Kart 8 Deluxe now displays the names of all the other upcoming cups as well. The names of the tracks arriving in tomorrow’s updates are also visible, but as you’d expect, that’s not true for the other ten cups.

The Golden Dash and Lucky Cat Cups will add three tracks from Mario Kart Tour and one each from Mario Kart 7, Mario Kart 64, Mario Kart Wii, Mario Kart DS, and Mario Kart: Super Circuit.
