Featuring courses from across the series, DLC tracks will arrive in Waves as part of the Booster Course Pass, with new tracks arriving two cups at a time. By the end of 2023 the courses will all be available - and until then, we’re left with datamines as to what to expect. If you are returning to Mario Kart 8 after a long spell, now is a good time to finish mopping up any remaining unlockables, including the elusive Gold Mario. On this page: Golden Dash Cup

Otherwise, Nintendo has yet to officially confirm the future tracks for Mario Kart 8 DLC. That said, datamines are giving us some indication. One, from MrNantendo on Twitter, shows a banner image with visuals of four tracks - Sydney Sprint and LA Laps from Mario Kart Tour, Mario Circuit on the SNES and Koopa Cape on the Wii - as well as possibly Rainbow Road (3DS), Vanilla Lake (SNES?), New York Minute (Tour), Sunset Wilds (Super Circuit) and Maple Treeway (Wii): Elsewhere, another datamine from Quaa in the Mario Kart Central discord (via kingdomharms on reddit) has suggested future courses will include the following, with some overlap with the above datamine:
DK Summit (Wii, reappeared in Mario Kart Tour)GCN Waluigi Stadium (Mario Kart Double Dash)LA Laps (Mario Kart Tour)Maple Treeway (Wii, reappeared in Mario Kart 7 and Mario Kart Tour)New York Minute (Mario Kart Tour)RMX Mario Circuit 1 (Mario Kart Tour)Singapore Speedway (Mario Kart Tour)SNES Mario Circuit 1 or 2 (SNES)Sunset Wilds (Mario Kart: Super Circuit, later released in Mario Kart Tour)Sydney Sprint (Mario Kart Tour)
Looking at Wave 2, some of these - including New York Minute - have been confirmed. Of course, take the above with a pinch of salt - but the reappearance of multiple Mario Kart Tour tracks (both original and remixed) is perhaps not a huge surprise.
