My pick of games that will/are selling well would be Zelda, Mario Kart, Arms, Splatoon 2, Fire Emblem Warriors, Mario Oddessy, Mario/Rabbids, Sonic, Xenoblade 2, Yooka Layee and maybe one of those Dragon Quest games. Im sure a lot of people will buy skyrim too, just for its portability. Plus this is only like the first year.
