You can get bundles with any pack-in you want, as long as it's Mario Kart.

Nintendo is seemingly the only console maker not raising prices this year and is in fact offering a form of discount.
The company today announced that their traditional holiday bundle will be available again, with a standard Switch, a Mario Kart 8 Deluxe download code, and a 12 month NIntendo Switch Online code for US$299.99 (ie: MSRP). For the first time, the same additions will be made to the Switch OLED, at its MSRP of $349.99.
Both bundles will be available starting next month. The OLED was bundled with Super Smash Bros. Ultimate last year.
