Switch 2 is likely coming in 2024. What do you think the major launch games will be? Not necessarily on launch day but in the launch period. Switch had BotW and then MK8D the next month.
I think MK9 is the most obvious. I wouldn't be surprised to see a 3D Mario during the launch window either. All the other major franchises seem to have had games release too recently or will be releasing later on Switch to be able to be launch period games for the next-gen.
I guess if we don't end up getting certain games on Switch (DK, Star Fox, Kid Icarus??, FZero...yes i know but a boy can dream) any of those could be launch period titles.
