I think the lack of the black Friday MK8 Switch bundle now will definitely make it difficult for the Switch 1 only version to outsell Wii Sports, but I think it should easily surpasses Wii Sports soon when including the Wii U version.
In Mario Kart World's case, i dont think the Switch 2's install base will be big enough for it to outsell Wii Sports. Im expecting Switch 2 to be around 130M lifetime which is a pretty big 30M lower than what Switch 1 sold. Im expecting this mainly cause of the Switch 2's price being on the higher end.
I also do think the 80$ price tag of MKW will also be a tougher pill to swallow for as many people to buy the game.
