I expect Nintendo will continue to follow the trend of 1-2 big AAA games (either from them or a third party) a month.
I think there’s a good chance of these AAA games in 2018:
-Animal Crossing
-Yoshi
-Kirby
-Fire Emblem
-Pikmin
-Smash Bros
-Wolfenstein
-No More Heroes
-Dragon Quest
That’s 9 AAA games (not including small indies) already. Means at minimum of one game a month would go to September.
There’s also a slim chance we see games in 2018 like:
-GTA
-2D MARIO
-Mario Maker
-Retro’s “secret” game
-Monster Hunter
-Metroid
-Pokemon
Along with every unknown game that may have started developed for the Switch either being port or original after successful Switch launch.
