Mario Kart 8 is basically May too, it's right at the end of April.
Switch will do fine. There's a good flow of digital content for the machine too, seems like a couple new games every week now.
Nintendo's summer in general is real solid IMO.
Mario Kart 8 Deluxe, Minecraft, Ultra Street Fighter II, NBA Playgrounds, ARMS, Sine Mora EX, Splatoon 2 and others.
