I’ve been pondering this for a bit

Because the Wii U’s name (technically) consists of two words, how would the prefix for 8’s courses be formatted? Wii U? WiiU? Wii-U? Maybe even just U? Probably even NS or NSW if they’re feeling it?

Also it’s pretty crazy how the Switch might not be represented with a prefix since MK10’s courses would likely use “NS2” as a prefix

The switch will, probably, get a prefix, since the battle Tracks are original of deluxe, I also don't know about the, not city Tracks, Tracks from Tour, since on the BCP they appear with no prefix, making it look like Nintendo considers them deluxe's Tracks

have you tried WU? (also it's MK9, dumb butt. (no offense))

i know you said no offense but you don't gotta call someone dumb butt for calling the next mario kart (which we dont even know will be named) mario kart 9

If the original mario kart 8 was on wii u then the prefix will be wii u

alright.

I'd agree if it wasn't for Gamecube(which to be fair NGC was already taken.)

Also Wii U is a bit long.

I think that the Wii U prefix might be UNS

Could be SW U
