Koei Tecmo is currently working on the announced Fire Emblem Warriors, a Fire Emblem game with a Dynasty Warriors-style gameplay. But that isn't the only game they're developing for the Switch.
They're very positive about the Nintendo Switch, actively working on Switch exclusives. Wall Street Journal reporter Takashi Mochizuki reported this in Koei Tecmo's most recent financial earnings briefing.
According to chairman Keiko Erikawa, their current game engine is capable of running multiplatform titles from a single source, which allows them to easily develop for the Switch.
Omega Force and Team Ninja, working under Koei Tecmo, are the developers for the upcoming Fire Emblem Warriors which is planned for both Nintendo Switch and 3DS. No release date is available as of yet.
