Here’s the list for those who don’t want to watch the video:

Athens Dash (Mario Kart Tour)

Daisy Cruiser (Mario Kart Double Dash)

Moonview Highway (Mario Kart Wii)

Squeaky Clean Sprint (brand new Mario Kart 8 Deluxe track)

Los Angeles Laps (Mario Kart Tour)

Sunset Wilds (Mario Kart Super Circuit)

Koopa Cape (Mario Kart Wii)

Vancouver Velocity (Mario Kart Tour)

I don't think they'll ever manage to top the Yoshi's Island track from the last wave. That was one of the coolest MK tracks ever. The music and visuals were amazing. Looking forward to this wave anyways though.

Really not a huge fan of the Tour tracks. They’re fine but they always feel poorly designed.

Mario Kart 8 Deluxe Wave 5 Tracks are out!... In 6 days. Why phrase the title as if they're out right now? Anyway I'm looking forward to these tracks. And I'm happy to see the returning characters. I wonder what the final wave has in store.

Edit: looks like the title was edited just after I commented. I'm still not used to the ability to edit titles here.

Too many Tour tracks, always flat and uninteresting to play.

The average quality of the others looks below the previous ones.

No reason to add Moonview Highway, another city track…

Happy to see Daisy Cruser, but seing the video, it looks less bouncy to play that the original one.

Does the purchase of the one booster pack get access to this too, or is this an additional $25? Not doing that silly online plus for half baked emulators.

KOOPA CAPPPEEEEE

I'm not sure if this is the first time I'm noticing it, or if it's actually the first time period, but I noticed they finally put anti gravity on these new tracks with Coopa Cape.

I'm increasingly disappointed by the tracks that don't look or feel at least a little bit like a race track. That includes the Tour tracks, but also things like Squeaky Clean Sprint. They're really cute and fun to look at, but it's gotten increasingly difficult to tell what is track and what is not.

Would some racing curbs kill the track designers?

Mario Kart is the gift that keeps on giving! I wonder where they can take the series from here. It's like Smash after Ultimate, I can't imagine what they'll do for the next title in the series, but I'm ready to be surprised 👍

Finally Daisy Cruiser! Best course from Double Dash

I got the NSO Expansion pack recently, but haven't tried the Mario Kart since, don't want to remove the TotK cartridge. Will give it a try soon though.

I like* how the houses in Athens look like toy blocks. There's a joke to be made here about the Greek economy.
Not sure how I feel about the inclusion of Moonview Highway, though. The Booster Course Pass already has a great many city tracks thanks to all the ones ported from Tour, and Moonview, as a traffic course at night, feels like it fits into the same kind of aesthetic and functional theming that N64 Toad's Turnpike from the base game does. The music might end up carrying my opinion on the track, though, like how 3DS Alpine Pass' does.

As soon as I heard the Koopa Cape song, I immediately went, yup this is gonna be a good one.

Strange they didn't show more of these in the direct if it was coming this soon after but ah well it's here now.

The visuals on the crowds in the background of the tour tracks does not look good, I know the visuals have been hit and miss for these tracks, but those are just flat out bad.

Nice to see new characters as well. We have Kamek, Petey Piranha, and Wiggler!!
