You know how action movie heroes creep through a quiet, dimly-lit area and mutter "It's quiet... too quiet" right before something horrible drops on their head? A lot of Switch owners get the same vibe when they look at Nintendo's 2019 release schedule. They’re currently in a big lull, but there's no doubt something is on the ceiling (probably some kind of Pokemon), and it's about to start salivating on them.
Granted, the Switch isn't the only system having a slow 2019. The first half of the year has been sleepy in general. EA's Anthem quickly fell off a cliff, and though games like the Resident Evil 2 remake, Devil May Cry 5, and Sekiro: Shadows Die Twice command happy buzz on social, there isn't a lot of "Wow-wee!" to their success. As Kat points out, the excellent indie title Katana Zero might be the only surprise thus far.
Aside from Katana Zero, the Switch's 2019 is largely being sustained by ports. Great ports, mind you, but ports nonetheless.
