2 packs coming. Each has 3 characters, 4 vehicles, and 2 cups (8 courses). http://mariokart8.nintendo.com/dlc/
"The Add On Content packs include classics like Wario’s Gold Mine from Mario Kart Wii, as well as new courses, some taking place in the worlds of The Legend of Zelda and Animal Crossing. New vehicles will also arrive with each pack, including the Blue Falcon kart representing the F-Zero franchise in the first AOC pack."
kinda lame to have another Mario and Peach though. and no Battle Arenas :(
Super Kart Bros.
The best part about this is defs the courses
