The day has come! The new Samus Aran adventure, Metroid Dread for Nintendo Switch is finally here! We are excited to share with the world what we have been cooking, taking part in development with Nintendo! The best part is that you can enjoy it this October! With all our love.

So, it's been confirmed that MercurySteam is the developer behind this, just like they were for Samus Returns.
Perhaps they'll be Nintendo's new partner for 2D Metroid much like Next Level Games is for Luigi's Mansion and AlphaDream was for Mario & Luigi (until they sadly went belly-up).
