What tracks should return in Mario Kart on the Wii U?

What tracks do you want to be returned in the next Mario Kart game on the Wii U? (considering that there are 4 retro cups with 4 tracks each)

MissingNo.
This is hard. Choosing courses from six games with only 16 tracks I'm allowed to choose. Well...
 * 1) SNES: Mario Circuit 3, Bowser Castle 3
 * N64: Toad's Turnpike, Sherbet Land, Royal Raceway
 * GBA: Sky Garden, Ribbon Road
 * GCN: Baby Park, Daisy Cruiser
 * DS: Delfino Square, Tick Tock Clock
 * Wii: Grumble Volcano, Rainbow Road
 * 3DS: Music Park, Piranha Plant Slide, Neo Bowser City
