Metroid: Samus Returns has been announced for Nintendo 3DS. A re-imaging of Metroid II: Return of Samus, it's a 2D-ish Metroid game that takes its design ideas from the past Metroid Prime games, as well as Other M. Despite what Plant said, it doesn't appear to have Fed Force in its lineage.

Metroid: Samus Returns is scheduled to release on September 15, 2017. It's a glorious time to be alive! Share your hype here!
