Kirby and especialy Yoshi will be good games, but I'm not hyped for it. However I'm hyped for Fire Emblem, Metroid Prime 4 and unannounced titles (I'm counting on Pikmin and Retro new IP!). Also Octopath Traveler and Shin Megami Tensei V are going to be really good.
2018 will be another great year for Nintendo, but maybe not that great as 2017.
