Some tracks I'd hope get some love:
GBA
Riverside Park - I can't see it as good as the original with the very varied shortcuts (bridge, corner cutters, shallow water path, etc) but it's solid in terms of theme. Could have some cool DK beats too.
Lakeside Park - A slightly less interesting version of the above.
Sunset Wilds - dope
Cheep Cheep Island - Really great potential for fantastic scenery here.
DS
Mario Circuit - IMO the absolute best circuit in all of MK
Desert Hills - cool SMB3 influence without being as broken as rDDD, nor as flat
Figure 8 Circuit - Needs no explanation why this is the most overdue track in all of MK, it's their last chance to correct this bug
Wii
Either Mario or Luigi Circuit, but not both - Daisy Circuit is overrated tbh, and we already have a bunch of city tracks with MKT now. LC and MC are more nostalgic simply because of the amount they appeared in ads and stuff in 08.
Dry Dry Ruins - Hype take on a desert map
7
Rock Rock Mountain - Just breathtaking
Rosalina's Ice World - Just chill
Apart from that there are some good stuff but I have some picks that are maybe not the most loved and would like to see some return
