For the ones which I know have concrete release dates:
>Zed (new game from some old members of Cyan Worlds), June 4
>Bloodstained: Ritual of the Night, June 18
>Catherine: Full Body's western release, September 3
>AI: The Somnium Files (Uchikoshi's new game), September 17
>Persona 5 The Royal, October 31
For the ones which might be coming out in the vaguely near future:
>Pathologic 2's Bachelor/Changeling routes
>Noita
>Creaks (the new Amanita Design game)
>Little Misfortune (new game from the Fran Bow devs)
>Hollow Knight: Silksong
>Ori and the Will of the Wisps
For the ones which may not ever come out:
>Spire (new game from Hitbox Team)
>UFO 50
>Environmental Station Alpha 2
>Bannerlord
And I'd be excited for quite a few more if I had a Switch, although the things I'm primarily looking forward to (Bayonetta 3, Metroid Prime 4 and Shin Megami Tensei V) all seem to be in some form of development hell.
