The Switch version of Mario Kart 8 will contain all of the previous Wii U content (tracks, characters) plus all of the Wii U DLC. This shouldn’t come as a surprise since the three minute Switch teaser showed two players racing through one of Mario Kart 8’s DLC tracks — GCN Yoshi Circuit. For those 3DS owners who skipped out on the Wii U, the Switch version of Mario Kart 8 should be a very tempting offer.
But why should Wii U owners care?
According to sources close to Nintendo, the Switch version of Mario Kart 8 will feature tons of exclusive content including brand new tracks, new playable characters, and a new-and-improved battle mode. That’s right, Nintendo listened to everyone’s criticisms about Mario Kart 8’s battle mode.
Mario Kart has completed development, and it’s planned to be released within the first three months of Switch’s launch.
