N64 Luigi Raceway is confirmed:

On a ledge it seems yeah.
Maybe just there for decoration, or perhaps a slower outer route with boosters that's pointless, kinda like gcn luigi circuit?

The large sand field makes me lean more towards MC2 (+ this track has a ramp already -> potential glider use).

I would be glad if Toad's turnpike 64 or Boo lake SC is confirmed

Just thinking... let's suppose there will be 2 SNES/N64/GBA/GC tracks (for a total of 8), and 4 DS/Wii tracks (for a total of 8). The confirmed tracks are:

SNES: Mario Circuit 2
N64: Luigi Raceway, Kalimari Desert,
GBA: Bowser Castle 1
GC: \
DS: Luigi's Mansion, Waluigi Pinball, DK Pass, Airship Fortress
Wii: Maple Treeway

This means the following number of tracks are missing:

1 SNES;
1 GBA;
2 GC;
3 Wii.

Which ones do you think will make it to MK7? Which ones would you like to be there?

(this was already done back in June, but we knew about less tracks than we do now.)

Are you sure BC1 and RMC2 are confirmed tracks?

I agree with Soro that Daisy Cruiser will be in the game, for the same reasons. The only other water tracks they could choose would be WII Koopa Cape or SNES Koopa Beach 1. And KB1 is nothing but water, so it wouldn't be a good choice for a retro track (unless nintendo doesn't want to spend more time).

Also no real old school ghost tracks are in yet (I say old school because LM is in already, but it's different). So I guess either Boo Lake or Broken Pier will be chosen from MKSC (personal guess is BL).

There are also no "city" tracks as a retro track yet, so I guess that either GCN Mushroom City or WII Moonview Highway will be in, but I think it will be MuC, because special cup tracks are mostly not used as retro tracks.

MKDS and MKWII both had 1 new ice track and 1 retro ice track. We haven't seen any new ice track yet, but I'm confident that there will be one. Also a Delfino Isle track is missing. This makes me think that WII Coconut Mall will be used as retro track. Kalimari Desert will be the only retro desert track I think. Finally I also think a SNES Donut Plains will be in.

Then nintendo usually fills the rest of the retro's with some fun tracks. So for MKWII it will be something like Toad's Factory and Wario's Gold Mine.

So my bet is on:

SNES Donut Plains 3
GBA Boo Lake
GCN Daisy Cruiser
GCN Mushroom City
WII Toad's Factory
WII Coconut Mall
WII Wario's Gold Mine

That's already the case, there is new snow track based on Mario Galaxy on the trailers.

Otherwise :

Those picks make sense and would make for a fairly balanced set of retro tracks, though there are many more interesting and unique tracks than Boo Lake in MKSC (fuck those ghost tracks anyway, lol). However, you're gonna bet they will put again another MC and BC in the mix instead

Fucking DK Cuntfucker Summit

Dino Dino Jungle from MKDD also confirmed !

Yay!
Always wanted to play that course.
Also, BC1 is definite, the video here: http://www.nintendo.co.jp/3ds/amkj/course/index.html shows it.
The vid of mushroom gorge is fucking weird, there's a blue mushroom in the cave with puts out a parachute, so the last corner will always be avoided now I suppose..

Also, I know they're not retro, but the mushroom cup courses look great!

transaltion of Mushroom Cup tracks

Toad Circuit (not MKW LC)
Daisy Hills (the level we saw her play in previous vids)
*something* Lagoon (water level of the demo vids)
Shy Guy Carnival (or Shy Guy’s? there’s no ’s though)

edit: translation of battle stages (these are harder so I could get them wrong)

GBA Battle Course 1
64 Big Donut
DS Southern Reef/Leaf (?) edit: checking the game, this seems to be Palm Shore…
??? House (Boo maybe?)
Sherbet Link
Wuhu Town

Thanks for the translations Michele, I was gonna ask someone to try them.

As for one of the new battle arenas it looks like it's from the second level of SMG with the bees. Likely the ??? House.
