My Wave 6 perditions

Acorn cup: Lame Avanti, Wario Coliseum Piranha Plant pipeline Piranha plant cove. Spiny Cup: Cairo/Madrid
GBA Luigi Circuit SNES BC3 and... DS RAINBOW ROAD

They Would Never Put Both Wario Colosseum And Waluigi Stadium In One Game Both As Retro Tracks (Not Including Tour).
DS Rainbow Road Just Straight Up Has No Chance.
dokan_course From MKDS Will (Most Likely) Never Be In Another Game And "DK" Probably Stands For "Donkey Kong" Or "Daisy Course".

my predictions are:

Acorn Cup:
Rome avanti
DK Mountain
Piranha Plant cove
mob_dk

Spiny Cup:
mob_md
Gcn Mushroom City/Dino Dino Jungle
Snes BC3/GBA BC4
Wii Rainbow Road

And why wouldn't they enhance Wii or Double Dash RR with antigravity rather than using a track that basically already did? Plus, DS Rainbow Road is much less popular than MKW's Rainbow Road, and the prefix leak doesn't suggest any more DS tracks (although that doesn't mean there for sure won't be one)

1. Wii Rainbow Road Is In Tour
2. The Prefix Leak Shows the Final Track Being a Wii One
3. Wii Rainbow Road Is More Popular

What if the third track of spine cup is wii RRd and then the final track is a track with everything that celebrates mario kart's history. sure it would be very long but still

My Wave 6 "perditions"

Didn't knew the wave 6 could make you lose your soul and fall into eternal damnation in hell, thanks for the warning!

yeah idk why I spelled it like that XD

LETS JUST SAY THAT WII RRd IS THE FINAL TRACK PROBLEM SOVLED.
also both athens and rome have pillar assets as trick ramps and that might be the case with madrid too. so we have only gotten one canadian city track so why wouldn't They make another one! TORONTO! (toronto transit)

your welcome!, come back any time!
