Other than a release date for Breath of the Wild 2, I'm not sure I'm holding out for too much...I'd be interested in that rumored Metroid Prime collection happening, I'm not super fond of the 2D games, but I remember generally liking the first one, even if it's an odd game in terms of being a first person shooter, but maybe they could have some alternate controls...or they won't, Nintendo isn't a big fan of options a lot of the time, but who knows lol
I guess if I had to pick something crazy, I'd love for that "Nintendo Kart" concept to exist, or to get a Diddy Kong Racing 2, give me a more exciting kart racer game.
