The Japanese Switch eShop has put up a date for Mario + Rabbids: Kingdom Battles’ Story Expansion DLC.
According to the listing the Story Expansion will be released on June 30, 2018. We believe this is a tentative date so it should be arriving anytime before June 30 worldwide.
Not a Nindie, but I think I stumbled upon the DLC date for the story expansion (atleast in JP) for #MarioRabbids… on the Japanese eshop listing for the expansion pass it lists this. @grantkirkhope @DavideSoliani #NintendoSwitch pic.twitter.com/RpDHUgGz8i
