+ 3rd parties like Injustice 2, Lego SW, Battlefield 1, Watch_Dogs 2, World of FF etc.
For the rest of the year:

For the future games like Metroid, Donkey Kong and Kid Icarus NX, Splatoon 2, Monolith's next game, and 3rd parties like Bravely Third, MonHun 5, Devil Summoner 3, Inazuma Eleven Ares and that new mecha game from L5.
