I kind of think this Gamestop rep would say more or less the same thing regardless of what is coming out. Smash is authentically a big game, but he could also say that Fire Emblem and Metroid Prime 4 are big surprises coming out this year. I am not expecting another really big first party game from Nintendo other than Smash Bros.
Now there might actually be a third party surprise coming. GTA 5 would authentically be a big surprise game that hasn't been announced yet for Switch. If there is a big surprise, I would guess it is something more like this.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
