The Future: Will There Be a 3.0.4 or 4.0.0?

With the Nintendo Switch 2 officially announced, speculation is rampant. Most experts believe 3.0.3 will be the final update for Mario Kart 8 Deluxe on the original Switch hardware. Nintendo is likely shifting development resources to the next Mario Kart title (tentatively titled Mario Kart X or Mario Kart 9) for the successor console.

However, if a major security flaw is found in online matchmaking, we could see a 3.0.4. But for now, 3.0.3 is the definitive, final version of the best-selling racing game on the Switch.
