It's a monumental day for the 3DS, as it's getting a pretty big exclusive in Detective Pikachu -- following a week that had the release of literally zero 3DS games, eShop or otherwise. The 3DS is also getting The Alliance Alive on March 27.
As for the Switch, the usual avalanche of titles is a go: Outlast 2, OPUS: Rocket of Whispers, NeoGeo World Heroes 2 Jet, Moon Patrol, Castle of Heart, Eat Beat Deadspike-san, Gekido Kintaro's Revenge, No Thing, Slayaway Camp: Butcher's Cut, Sol Divide - Sword of Darkness -, and Warp Shift.
