Nintendo finished their jam-packed Nintendo Direct with one last big announcement. They really smashed it with this one.
Super Smash Bros. for Nintendo Switch has been confirmed for release in 2018, as easily the biggest game announcement that Nintendo have for this year.
There’s literally nothing else that we know right now, but with the way that the game was introduced, we’d expect this to be something much, much more than a simple port of the Wii U version of the game. For one thing, the Inkling Boy and Inkling Girl are almost certainly a part of the game’s roster.
