While the sighting and Robinson's comments have generated renewed attention, Nintendo has not issued any official confirmation.
The Metroid franchise has a long history on Nintendo hardware, most recently with Metroid Dread, which was released for the Nintendo Switch in October 2021 and developed by MercurySteam.
That title marked the first original side-scrolling Metroid entry in many years and received critical acclaim for its level design and faithful continuation of the series' exploration-focused gameplay.
On the 3D side, Metroid Prime 4 remains a notable point of interest.
Nintendo announced in 2019 that Retro Studios would be overseeing development after an earlier restart; however, Nintendo has not announced a release date or further details about Metroid Prime 4.
Retro Studios is best known for its work on the Metroid Prime trilogy and other Nintendo collaborations.
Regarding the recent reports, Robinson responded to coverage of the Brazil rating listing by indicating that more than one Metroid project could be underway.
In journalistic terms, Robinson conveyed that multiple Metroid-related releases may be in development and that fans should be attentive to forthcoming news, though he did not provide specifics.
At present, the verifiable facts are limited: a reported rating entry for a title named 'Metroid Ravenous' was spotted on a Brazilian ratings website, and a senior VGC editor has publicly suggested additional Metroid activity based on sources.
Beyond those reports, Nintendo has made no formal announcements via Nintendo Direct, press release, or the Nintendo eShop that would confirm a new Metroid release or its platforms.
For readers tracking the franchise, the clearest confirmations remain Metroid Dread (MercurySteam, 2021) and the ongoing, officially acknowledged development status of Metroid Prime 4 with Retro Studios.
Any further updates will need to come directly from Nintendo or verifiable publisher filings.
