My switch is collecting dust for more than 6 months. Nintendo need to release good game very soon
Nothing big is coming out until far later in the year and that isn't a given.
If you like the look of Mario Golf that is coming late June.
A lazy port of a port in Skyward Sword HD is coming out mid-July.
Pokemon Snap is coming out this week if that floats your boat.
Outside that you are looking at ports of old more niche games and indie games.
The Switch calendar has been junk for quite a while now with ports and indies being relied on to prop it up.
