LOS ANGELES—During a livestreamed presentation Tuesday morning, Nintendo announced a "core Pokemon RPG" title, as well as an in-development sequel to the Metroid Prime series, both for Nintendo Switch.

The Game Freak-developed Pokemon RPG "may not release for more than a year, but we hope you look forward to it all the same," Pokemon Company's Tsunekazu Ishihara said on the stream. "What kind of Pokemon game will we be able to play on Nintendo Switch? I'm looking forward to trying it myself," Nintendo's Shinya Takahashi added. The company did not offer further information.

For Metroid Prime 4, Nintendo didn't provide any information other than a logo set on a black backdrop and the fact that it is "currently in development for Nintendo Switch." That fact alone is sure to excite fans who have been clamoring for a continuation of a series that has laid dormant since the Wii release of Metroid Prime 3 in 2007. The lack of even an in-development screenshot, though, suggests that the sequel won't be available for a while. A quick peek at prior series developer Retro Studios' social media accounts offers no indication just yet that the series' co-creators are returning for this one.

[Update: Nintendo of America Marketing Chief Bill Trinen confirmed on stream that Retro Studios is not working on Metroid Prime 4. Instead, Nintendo producer Kensuke Tanabe, who produced the first Metroid Prime, will oversee the project with his own team. Tanabe also worked on Metroid Prime: Federation Force and Paper Mario: Color Splash]
