i'm kinda excited :)
split into 2 packs, $10 each or $16 for both. preorder nets you 8 different colours for yoshi and shyguy immediately.
first pack is zelda themed and lands in nov, has link, tanooki mario and cat peach, 4 vehicles including blue falcon and 8 tracks.
second pack is animal crossing themed and lands in may 2015, has villager, isabelle and dry bowser, 4 vehicles and 8 tracks.
tracks appear to be 4 each for cups, so a zelda and animal crossing cup, possible the last 2 will be retro cups.
oooh boy, Nintendo has joined the ranks. Not a fan of DLC's personally, but i'm sure they appeal to some people.
