Now that we have a pretty thorough idea of what the game offers, how much do you expect it will sell lifetime, and what is your reasoning for your estimate?

For comparison's sake, Mario Kart 8 Deluxe has so far sold 67.35 million, and Mario Kart Wii sold 37.38 million.

I expect a lower attach rate than MK8 Deluxe, but not by much.

1 for every Switch 2 sold.

40-50 Million. I dont think it will do as well as MK8D.

The sales are going to be heavily tied to hardware sales, and as I expect Switch 2 to sell less I expect MKW will also sell less than MK8DX. 40-50m.

I can see 70M+ if the bundle counts

I think it's safe to say it will race past Mario Kart Wii, but I still think it will finish notably behind 8 Deluxe.
I voted 40-50 million and I'll say about 45 million units.

I think MK8D will be king when it’s all said and done

I could see it selling like ~40m instead of the 60m+ the Switch did.
The price the backlash, might have a effect here.

About 10 million like the Wii-U version. I'm really not seeing that many people hyped for the Switch 2.
