What will Mario Kart 9's Wario track be like?

[CM30]

As you know, almost every Mario Kart game has a Wario themed track of some kind or another:

1. Mario Kart 64: Wario Stadium
2. Mario Kart Double Dash: Wario Colosseum
3. Mario Kart DS: Wario Stadium
4. Mario Kart Wii: Wario's Gold Mine
5. Mario Kart 7: Wario's Shipyard/Galleon
6. Mario Kart 8/Deluxe: Mount Wario

So, what do you think the new one will be for Mario Kart 9?
