I am not putting Metroid or Bayonetta 3 because I have no clue when those two started development. Anyway...
January - NSMBWiiU
February - Nothing Important
March - Fire Emblem
April - Animal Crossing
May - Yoshi
June - Town
July - Daemon X Machina
August - Something unannounced
September - Something unannounced
October - Luigi's Mansion
November - Pokemon
December - Nothing. Well maybe an RPG from Monolith Soft. #Xenoblade X port
Honestly if Bayo 3 and Metroid come this year. My guess is that Metroid will be September and Bayo will be August. Also, Shin Megami Tensei V is not coming this year. That's a 2020 or 2021 title Atlus is like Square. They announce games way too early.
